Mina version managers plugin

[lovro-bikic]

Mina currently supplies tasks for version managers chruby, rbenv, rvm and ry. Since there is interest in supporting other managers (see #625, #667), we've decided to extract all version manager tasks to a separate gem and continue to add support for new managers there.

This change will be implemented in three steps:

• Release a gem for version manager tasks. It will initially support all managers Mina currently supports.
• Release Mina 1.3.0 which will print a deprecation warning for tasks which will be removed in 2.0.0.
• Release Mina 2.0.0 which will remove all version manager tasks from Mina.

Is there a repo for the version manager gem?

Not at the moment, this is still being worked on.
