Add command to start project and go to shell

[omarcinkonis]

In every development session, I use devenv up -d && devenv shell to run the project and access required tools. When I'm done, I have to exit twice: 1) exit the shell and 2) run devenv processes down.

This process could be streamlined into a single command that:

• starts the project
• drops the user into a shell with project tools
• on exit, stops processes and exits the shell

How about devenv shell --up?

A flag can introduce confusion because it's not clear where it should go, devenv shell -up or devenv up --shell. Yesterday, before submitting this issue, I read devenv --help and devenv up --help to check if a flag is already implemented. I somehow didn't figure I should also check devenv shell --help. This is the kind of confusion I'm talking about.

I suggest devenv dev. I think it's a good name for a command that ties the whole development loop.

Another argument not to use "up" is that it raises question whether I should run "down" when I'm done.
