Improve Eclipse Che deploy / update flow

[mmorhun]

What does this PR do?

This PR contains several changes:

• Now chectl is able to deploy embedded (the same as cli) version of Che and all (with some limitations) previous versions.
• Added version flag to server:deploy command, that downloads templates for older versions. For future versions, update of chectl is required (so far the limitation is UX not technical).
• Added warning message for each command if newer chectl is available. For server:deploy and server:update commands interactive prompt is added.
• Deleted outdated installer minishift-addon.

I think it's odd because I might expect that -v or --version will display the current version of the cli

The flag is used as an argument for server:deploy command, so it will not collide with -v flag of chectl itself.
