add a task to open a database console

[djordjelacmanovic]

Added support for running rails dbconsole, which opens an interactive command line interface to the app's database.

Thanks for the PR, however, we decided not to add this functionality to core. The reason is, we already support executing arbitrary Rails/Rake tasks, which you can invoke from CLI like this:

mina "rails[dbconsole]"

This will have the same effect as your proposed solution.

If you use this task often, you can also add it to your config/deploy.rb:

task :dbconsole do
  invoke :rails, 'dbconsole'
end

which you can then invoke from CLI: mina dbconsole

You can do the same with Rake tasks: mina "rake[dbconsole]"
