python-smartpm: add ignore-recommends package flag

Adds support for a flag that is saved into Smart's configuration against
a package that says it should not be installed if it is only recommended
by a package being installed rather than required. This will enable us
to add BAD_RECOMMENDATIONS support for RPM.
