This needs to be done before we switch back from codfw to eqiad:
Enable replication on codfw masters from eqiad on (with GTID disabled):
[x] s1
[x] s2
[x] s3
[x] s4
[x] s5
[x] s6
[x] s7
[x] s8
Double check the following sections have it enabled (it has not been disconnected):
[x] x1
[x] es4
[x] es5
[x] pc1
[x] pc2
[x] pc3
[x] Check and disable GTID on codfw/eqiad masters for the above sections.
[x] Check that all eqiad slaves have GTID enabled
[x] Check which notifications are disabled for eqiad hosts
[x] Check event scheduler is enabled on eqiad hosts
[x] Check that query killers are installed and enabled on eqiad hosts
[x] Check semisync
