A redis connector of type single or sentinel always got a timeout error
when doing the connector test in the dashboard if no username or
password was provided. This commit makes sure that the user instead get
an informative error message. Additionally, this commit adds more
more error information for all redis connector types.

Before this commit, generic validation errors were reported as union
mismatches of _all_ of the bridge schemas. After this commit, specific
schema is chosen before validation.
Before this commit the following happened sometimes:
1. action status is connected
2. action config is updated to something that should change the status to
disconnected
3. action status is still connected and the old config is being used by
the connector even though the config has been correctly updated.
The reason for this bug is that the post_config_hook runs before the
global EMQX config is updated. The post config hook is adding the new
config to the connector. Since the new config causes the action to get
status disconnected, the adding of the action to the connector is
retried when the health check runs but this time the config will be
loaded from the global config which could cause the old config to be
loaded (this happens when the global config has not had time to get
updated).
The above problem has been fixed in this commit by only reading action
configs from the global config when the connector starts/restarts and
instead store the latest configs for the actions in the connector.

Previously a batch of requests that was sent to a connector could
contain both requests with the stop_after_rendering flag and requests
without this flag. When this happened a warning message was generated and
the stop_after_render flags for the batch would be ignored. This commit
fixes so that a mixed batch is never created so there is no longer any
need for a warning message or ignoring flags.

Although the frontend doesn't send `enable` when creating a bridge/action/connector, the
default value in the schema is `true`, so when attempting to fetch it from the raw config
we should adhere to that default.
