Add umask option to pip module
On systems with restrictive umasks, the pip module won't allow you to install pip packages that are usable by everyone on the system. This commit adds a umask option to optionally override the umask on a per-package basis.

- The system umask to apply before installing the pip package. This is
|
||||
useful, for example, when installing on systems that have a very
|
||||
restrictive umask by default (e.g., 0077) and you want to pip install
|
||||
packages which are to be used by all users. Note that this requires you
|
||||
to specify desired umask mode in octal, with a leading 0 (e.g., 0077).

- Please note that virtualenv (U(http://www.virtualenv.org/)) must be installed on the remote host if the virtualenv parameter is specified and the virtualenv needs to be initialized.
