[PATCH v2 12/14] provision: Add support for provision filter tags

[Denis Kenzior <denkenz@gmail.com>]

oFono main.conf configuration file can now contain an entry with group
'Provision' and key 'TagsFilter'.  This entry is treated as a comma
separated list of all tags that are accepted during context
auto-provisioning.  This can help to filter duplicate context entries
from the provisioning database such that context auto-provisioning is
successful without user intervention.
