MXS-1565: Invalid rejoin test
- 1 master, 3 slaves - stop maxscale so it does not autorejoin later on - stop & reset slave on servers 3 & 4 - add data to server 4 - restart maxscale, check that server 3 is rejoined but not server 4 - manually set server 1 to replicate from server 4, creating a relay master - check that servers 2 & 3 are redirected, making server 1 just a slave - switchover master to server 1, check that it's the master Also, moved some common functions into their own files. These functions are used by multiple tests.
