Allow specifying an ACL log reason, which is shown in the log. Right now it always shows "unknown", which is a little bit cryptic. This is a breaking change, but this API was added as part of 7 so it seems ok to stabilize it still.

The PR extends RM_Call with 3 new capabilities using new flags that are given to RM_Call as part of the `fmt` argument. It aims to assist modules that are getting a list of commands to be executed from the user (not hard coded as part of the module logic), think of a module that implements a new scripting language... * `S` - Run the command in a script mode, this means that it will raise an error if a command which are not allowed inside a script (flaged with the `deny-script` flag) is invoked (like SHUTDOWN). In addition, on script mode, write commands are not allowed if there is not enough good replicas (as configured with `min-replicas-to-write`) and/or a disk error happened. * `W` - no writes mode, Redis will reject any command that is marked with `write` flag. Again can be useful to modules that implement a new scripting language and wants to prevent any write commands. * `E` - Return errors as RedisModuleCallReply. Today the errors that happened before the command was invoked (like unknown commands or acl error) return a NULL reply and set errno. This might be missing important information about the failure and it is also impossible to just pass the error to the user using RM_ReplyWithCallReply. This new flag allows you to get a RedisModuleCallReply object with the relevant error message and treat it as if it was an error that was raised by the command invocation. Tests were added to verify the new code paths. In addition small refactoring was done to share some code between modules, scripts, and `processCommand` function: 1. `getAclErrorMessage` was added to `acl.c` to unified to log message extraction from the acl result 2. `checkGoodReplicasStatus` was added to `replication.c` to check the status of good replicas. It is used on `scriptVerifyWriteCommandAllow`, `RM_Call`, and `processCommand`. 3. `writeCommandsGetDiskErrorMessage` was added to `server.c` to get the error message on persistence failure. Again it is used on `scriptVerifyWriteCommandAllow`, `RM_Call`, and `processCommand`.

This implements the following main pieces of functionality: * Renames key spec "CHANNEL" to be "NOT_KEY", and update the documentation to indicate it's for cluster routing and not for any other key related purpose. * Add the getchannels-api, so that modules can now define commands that are subject to ACL channel permission checks. * Add 4 new flags that describe how a module interacts with a command (SUBSCRIBE, PUBLISH, UNSUBSCRIBE, and PATTERN). They are all technically composable, however not sure how a command could both subscribe and unsubscribe from a command at once, but didn't see a reason to add explicit validation there. * Add two new module apis RM_ChannelAtPosWithFlags and RM_IsChannelsPositionRequest to duplicate the functionality provided by the keys position APIs. * The RM_ACLCheckChannelPermissions (only released in 7.0 RC1) was changed to take flags rather than a boolean literal. * The RM_ACLCheckKeyPermissions (only released in 7.0 RC1) was changed to take flags corresponding to keyspecs instead of custom permission flags. These keyspec flags mimic the flags for ACLCheckChannelPermissions.

SET is a R+W command, because it can also do `GET` on the data. SET without GET is a write-only command. SET with GET is a read+write command. In #9974, we added ACL to let users define write-only access. So when the user uses SET with GET option, and the user doesn't have the READ permission on the key, we need to reject it, but we rather not reject users with write-only permissions from using the SET command when they don't use GET. In this commit, we add a `getkeys_proc` function to control key flags in SET command. We also add a new key spec flag (VARIABLE_FLAGS) means that some keys might have different flags depending on arguments. We also handle BITFIELD command, add a `bitfieldGetKeys` function. BITFIELD GET is a READ ONLY command. BITFIELD SET or BITFIELD INCR are READ WRITE commands. Other changes: 1. SET GET was added in 6.2, add the missing since in set.json 2. Added tests to cover the changes in acl-v2.tcl 3. Fix some typos in server.h and cleanups in acl-v2.tcl Co-authored-by:

Summary of changes: 1. Rename `redisCommand->name` to `redisCommand->declared_name`, it is a const char * for native commands and SDS for module commands. 2. Store the [sub]command fullname in `redisCommand->fullname` (sds). 3. List subcommands in `ACL CAT` 4. List subcommands in `COMMAND LIST` 5. `moduleUnregisterCommands` now will also free the module subcommands. 6. RM_GetCurrentCommandName returns full command name Other changes: 1. Add `addReplyErrorArity` and `addReplyErrorExpireTime` 2. Remove `getFullCommandName` function that now is useless. 3. Some cleanups about `fullname` since now it is SDS. 4. Delete `populateSingleCommand` function from server.h that is useless. 5. Added tests to cover this change. 6. Add some module unload tests and fix the leaks 7. Make error messages uniform, make sure they always contain the full command name and that it's quoted. 7. Fixes some typos see the history in #9504, fixes #10124 Co-authored-by:

This commit introduced a new flag to the RM_Call: 'C' - Check if the command can be executed according to the ACLs associated with it. Also, three new API's added to check if a command, key, or channel can be executed or accessed by a user, according to the ACLs associated with it. - RM_ACLCheckCommandPerm - RM_ACLCheckKeyPerm - RM_ACLCheckChannelPerm The user for these API's is a RedisModuleUser object, that for a Module user returned by the RM_CreateModuleUser API, or for a general ACL user can be retrieved by these two new API's: - RM_GetCurrentUserName - Retrieve the user name of the client connection behind the current context. - RM_GetModuleUserFromUserName - Get a RedisModuleUser from a user name As a result of getting a RedisModuleUser from name, it can now also access the general ACL users (not just ones created by the module). This mean the already existing API RM_SetModuleUserACL(), can be used to change the ACL rules for such users.
