The BMP implementation currently only supports global and
loc-rib instance types. When loc-rib is selected, the
peer_distinguisher is set to the route distinguisher of
the L3VRF where the BGP instance is. This functionality has
not been tested until now, because the peer distinguisher
value had been explicitly omitted in the bmp messages.
Expose the peer distinguisher value in all BMP messages
received. This change requires to modify the expected output
for loc-rib when the BGP instance is in a L3VRF.
The handling of peer distinguisher value for RD instances
will follow in the next commits.

For those tests using exabgp convert them all to use `neighbor X timers
connect 1`. I have noticed that occassionally when looking at the
support files for tests run that peers are in a wait period for
reconnecting which is longer than the test is waiting to converge.

Some temporary files are hardwritten in /tmp folder. Use the bmp log
folder instead. Replace the bmp log file argument with bmp log folder.

DEBUG_PCAP can be set True to manually enable pcap debugging when
running bmp tests.
Save bmp pcap in logdir (ie. /tmp/topotests/bgp_bmp.bgp_bmp_X/ instead
of /tmp.

Multiple BMP tests can run in parallel but, when one instance ends,
it kills the BMP server process of all BMP tests.
Save the PID of a BMP server and only kill it at the end.

When configuring the bgp_bmp test with an additional
peer that sends empty AS-PATH, the bmp collector is stopping:

The parser attempts to read an empty AS-path and considers the length
value as a length in bytes, whereas RFC mentions this value as
definining the number of AS-PAths. Fix this in the parser.

The bgp_bmp and bgp_bmp_vrf tests use similar routines
to test the bmp, but are duplicates. Gather the bgp_bmp
and the bgp_bmp_vrf tests in a single bgp_bmp folder.
- Create a bgpbmp.py library under the bgp_bmp test folder
- The bgp_bmp and bgp_bmp_vrf test are renamed to bgp_bmp_1
and bgp_bmp_2 test.
- Maintain separate folder for config and output results. Adapt
the bgp_bmp library accordingly.
- The json output for bgp_bmp_2 test has no referenc to hostame.
