Change subject: [WIP/POC/POS] Add python version of maintain-replicas script
......................................................................
[WIP/POC/POS] Add python version of maintain-replicas script
This does not include functionality that was split into maintain-meta_p.py last
year.
This (so far) deals with the following issues:
* It was written in Perl.
* Configuration was part of the script.
* It tried to parse ~/.my.cnf instead of getting them from it's own
configuration.
* Configuration file couldn't be specified on the CLI
It still needs to:
* Allow specifying one database to work on only.
* BE TESTED.
* Be commented more
* Do less work in file scope?
* Pause and ask for confirmation of things
* Have a "dry run" mode.
* Be more verbose.
* Be more helpful to the user in case of failure.
