repoview: move subsettable in a dedicated module

The dictionary got moved in `branchmap` to avoid import cycle. However, we are
about to needs it in repoview too. So we introduce a now module to define that
that mapping.

### Nearest subset relation
# Nearest subset of filter X is a filter Y so that:
# * Y is included in X,
# * X - Y is as small as possible.
# This create and ordering used for branchmap purpose.
# the ordering may be partial
subsettable = {None: 'visible',
               'visible-hidden': 'visible',
               'visible': 'served',
               'served.hidden': 'served',
               'served': 'immutable',
               'immutable': 'base'}
