The DynamoDB connector status checks takes very long when the server is
unavailable which makes the resource manager blocked for a long time.
This causes calls to update the Bridge config with the Bridge V1 API fail
due to a timeout when it calls the resource manager to remove the
channel.
A better fix would be to change the resource manager so that the status
check cannot block it for a long time. However, this is more complicated
so it needs to be done in a later commit. A new ticket has been created
for this task https://emqx.atlassian.net/browse/EMQX-12015 .
