Re-ordering this file so it's clearer what needs to happen next.

RestartSlave conversion to RPC.
BreakSlaves is now a RPC.

- schema was broken by my RPC conversions
- reparent doesn't need special casing, 2m timeout is default.

Fix charset handling in filtered replication.
Converting hook execution to RPC.

Now the rest is all streaming RPCs.
Merge branch 'charset'
Cosmetic change: rename VtGateParams to TestEnv
Remove unused go-etags setup in dev.env.
Converting schema commands to RPCs.

Originally I wanted to use streaming RPCs, but there is nothing
to communicate back while the changes are applied, so no reason.
