Bug#31005815 MTR: ALLOCATE PORTS FOR THE MYSQLD ADMIN INTERFACE
The mysql server allows a separate administrative connection channel to privileged administrators( having SERVICE_CONNECTION_ADMIN) where in the max_connections limit doesn't apply. In MTR, there is no port reserved for the admin interface. For tests which use the admin channel, a workaround to use the very next port which mysqld uses is currently being employed. This works for tests which use a single mysqld server but is not ideal and there is a need to support this mechanism within MTR itself. The patch adds a dedicated port for each mysqld server which can be used for the admin interface and updates tests which have the workaround to use the allocated port. Please note that this change only sets --admin-port but not --admin-address so that the admin channel is not setup by default and doesn't affect the test suite. Any test which requires the admin interface can set the option --admin-address to enable the admin interface. Change-Id: I1b9ece250d2fd28531c61f69dbb889d9fe14447f
