Several bridges should be able to share a connector pool defined by a
single connector. The connectors should be possible to enable and
disable similar to how one can disable and enable bridges. There should
also be an API for checking the status of a connector and for
add/edit/delete connectors similar to the current bridge API.
Issues:
https://emqx.atlassian.net/browse/EMQX-10805
Due to:
* Cluster RPC MFA is not idempotent!
* There is a lack of rollback for callback's side-effects
For instance, when two nodes try to add a cluster-singleton
concurrently, one of them will have to wait for the table lock
then try to catch-up, then try to apply MFA.
The catch-up will have the singleton created, but the initiated
initiated multicall apply will fail causing the commit to rollback,
but not to 'undo' the singleton creation.
Later, the retries will fail indefinitely.
