Ability to run a bash command on Reload

[mrcampbell]

My project runs off a bash file, and so to run my app I run the command ./run -d (d being a flag for "development").

Rather than running a .go file, this should be able to have a custom command at runtime.

I'm willing to work on this if there's nothing in the works!

For others looking here, you can already do that using the scripts key (It can be found in the readme config sample).

          scripts:
              - type: before
                command: echo hello before every reload
                output: true

The above runs the command on every reload. if you need it to run once, you can include global as follows:

          scripts:
              - type: before
                command: echo hello before any other command on startup only
                global: true
                output: true
