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.

emqx_bridge
EMQX Data Bridge is an application that managing the resources (see emqx_resource) used by emqx rule engine.
It provides CRUD HTTP APIs of the resources, and is also responsible for loading the resources at
startup, and saving configs of resources to data/ after configs updated.
The application depends on emqx_connector as that's where all the callback modules of connector
resources placed.
