[OE-core] [PATCHv2 1/3] package_manager.py: Move opkg_query() outside of Indexer class

[mariano.lopez at linux.intel.com]

From: Mariano Lopez <mariano.lopez at linux.intel.com>

When using the opkg and apt-get package managers the function
opkg_query() can be useful when query for package information.

This change moves the function outside the Indexer class so
the Indexer, OpkgPM, DpkgPM can benefit from it.
