Test BGP conditional advertisement functionality.

| R1 |------------| R2 |------------| R3 |
| | | | | |
+--------+ +--------+ +--------+
R2 is DUT and peers with R1 and R3 in default bgp instance.
Following tests are covered under BGP conditional advertisement functionality.
Conditional advertisement
-------------------------
TC11: R3 BGP convergence, without advertise-map configuration.
All routes are advertised to R3.
TC21: exist-map routes present in R2's BGP table.
advertise-map routes present in R2's BGP table are advertised to R3.
TC22: exist-map routes not present in R2's BGP table
advertise-map routes present in R2's BGP table are withdrawn from R3.
TC31: non-exist-map routes not present in R2's BGP table
advertise-map routes present in R2's BGP table are advertised to R3.
TC32: non-exist-map routes present in R2's BGP table
advertise-map routes present in R2's BGP table are withdrawn from R3.
TC41: non-exist-map route-map configuration removed in R2.
advertise-map routes present in R2's BGP table are advertised to R3.
TC42: exist-map route-map configuration removed in R2
advertise-map routes present in R2's BGP table are withdrawn from R3.
Conditional advertisement along with Route-map Filter
-----------------------------------------------------
TC51: exist-map routes present in R2's BGP table, with route-map filter.
All routes are withdrawn from R3 except advertise-map routes.
TC52: exist-map routes present in R2's BGP table, without route-map filter.
All routes are advertised to R3 including advertise-map routes.
TC53: non-exist-map routes present in R2's BGP table, with route-map filter.
All routes are withdrawn from R3 including advertise-map routes.
TC54: non-exist-map routes present in R2's BGP table, without route-map filter.
All routes are advertised to R3 except advertise-map routes.
TC61: exist-map routes not present in R2's BGP table, with route-map filter.
All routes are withdrawn from R3 including advertise-map routes.
TC62: exist-map routes not present in R2's BGP table, without route-map filter.
All routes are advertised to R3 except advertise-map routes.
TC63: non-exist-map routes not present in R2's BGP table, with route-map filter.
All routes are withdrawn from R3 except advertise-map routes.
TC64: non-exist-map routes not present in R2's BGP table, without route-map filter.
All routes are advertised to R3 including advertise-map routes.
i.e.
+----------------+-------------------------+------------------------+
| Routes in | exist-map status | advertise-map status |
| BGP table | | |
+----------------+-------------------------+------------------------+
| Present | Condition matched | Advertise |
+----------------+-------------------------+------------------------+
| Not Present | Condition not matched | Withdrawn |

Here in this topology, based on the default route presence in R2 and
the configured condition-map (exist-map/non-exist-map) 10.139.224.0/20
