[Feature request] Support mysql --login-path

[sjn]

Hei,

I've been recently made aware of the mysql-config-editor tool, and it's corresponding --login-path=name argument to mysql. It seems to me that there could be some conceptual (and convenient!) overlap between this and sqitch targets.

Is this something that could/should be implemented in sqitch?

This feature is available in mysql-5.6 and later.

Yeah, mysql already will, but not Sqitch's use of DBD::mysql. Happy to see this added if anyone has the TUITs.
