BSC_Tests: count MGCP operations in as_media
as_media handles the MGCP interaction for most of the tests. However,
it does not make sure if transactions are missing or if too many
transactions are performed (e.g. if an SCCP-Lite tests still creates
the connections pointing to the core network, even if they must not
created by the BSC in this case). So lets make sure that the MGCP
transactions are performed as expected by counting them.
- Add counters to count CRCX and MDCX transactions
- Check those counters after call establishment and handover
