s3: better check for walrus

Check for Walrus endpoint by looking to see if the endpoint is not AWS.

Ensure non-root users can read arguments file when using sudo_user and non-standard modules

Non-standard modules must read in the arguments file in order to access their arguments, however, when this file is transfered to the remote host it may only have the permissions 600.

'easy_install' executable, modeled on '_get_pip'
from the 'pip' module to correctly handle all combinations of explicit
executable and virtualenv.

path explicit executable is passed to the task and to look for an explicit executable
by basename in a virtualenv if that is specified.

New module argument to specify the executable used for running 'pip'. This allows support for system installation of packages on systems with multiple installations of Python.
