[PATCH] python-smartpm: Add an attempt install mode

[Mark Hatle <mark.hatle@windriver.com>]

[ YOCTO #3723 ]

Add a mode to smart that will allow an installation to continue, instead of
failure in the case that one or more items is uninstallable.

Uninstallable packages are simply ignored, and no error is generated.

+Add a mechanism to attempt the install operation, w/o failing.
+
+For complementary and 'attemptonly' packages, we need a way to instruct smart to
+try to install, but ignore any failures.
+
+This option only works for the install operation.
