Restarting a server instance to change the interserver password results
in many replicas being out of sync until all clusters are using the new
credential.
This commit adds dynamic credential loading for both the client
(Replicated* tables) and server (InterserverIOHTTPHandler).
This commit also adds the ability to rotate credentials, i.e. accept more
than one credential during a credential change.
