Postdoc

Initial release

Add better support for controlling the output via command flags.

For example, with these aliases:


alias dphd="phd --postdoc-dry-run"
alias qphd="phd --postdoc-quiet"


running `dphd psql` will print the connection args and that's it. This may be useful if you're doing something like `docker run --env PGPASSWORD=hunter2 pg94-util $(dphd psql)`.

running `qphd psql` is useful if you're logging stderr and don't want that extra output `phd` will spit out.

This was the error users would see:

bash
Traceback (most recent call last):
File "/usr/lib/python2.7/subprocess.py", line 1249, in _execute_child
raise child_exception
OSError: [Errno 2] No such file or directory


Environment variables are passed into the `env` kwarg now instead of in the process name.
