BTS_Tests: add testcase TC_paging_imsi_200percent_with_ps
The current paging load tests only test what happens when the paging
load is introduced from the PS side. However there are no tests that
tests what happens when PS pagings are introduced from the PCU side
into an already overloaded system.
osmo-bts was equipped recently with a mechanism that detects congestive
situations. Once a congestion is detcted osmo-bts will drop pagings from
the BTS side. The rationale of the new testcase is that the behavior
must not change when the PS pagings start since osmo-bts is dropping
them.
