Rework ssh_keys_pillar-related states

Adding support for the enforce_password option.

This will allow users change their passwords after the initial setting in Salt.

the user's .ssh directory should be created if ssh_auth_file is supplied

SSH key pairs deployed via the user's ssh_keys_pillar dict aren't
handled the same as the user's ssh_keys, e.g., file ownership and
permissions aren't specified, and the keying material gets copied
directly into the SLS file.  This change rewrites the two templated
file.managed states to behave as follows:

  - set the files' owner to be the user

  - set the files' group to be the user's primary group

  - for the public key, set the mode to 644 (u=rw,go=r)

  - for the private key, set the mode to 600 (u=rw,g=)

  - pull the files' contents directly from pillar

Some smaller changes.

Add vimrc extension

This will ensure that a given vimrc file in a users home dir is managed

If this isn't found it will install salt://users/files/vimrc/vimrc

Added bashrc extension to users-formula

This will ensure a given bashrc file in a users home dir.
