Make deployment prep have continuous replication lag
Open, LowestPublic

Description

Replication lag in production can cause weird issues that are very hard to debug. Now that we run automated integration tests, always having a replication lag in our deployment environment may surface issues that developers usually are not aware of, and help us create better code.

From bug 60058

setting the lag is fairly trivial, percona makes a tool for it called
pt-slave-delay.

That, and we need to have slaves setup first...

Marking to lowest priority since nobody is sponsoring this for now.
