the BSC configuration currently only offers A50 (no) encryption.
Since the TTCN3 tests also cover assignment tests with encryption
and osmo-bsc now supports multiple cipher settings at a time this
setting should be extended accordingly.
- Also enable A51 and A53 encryption.
Ideally we would want to launch a group of containers with their own
private network segment and use the same static IP addresses in those
isolated networks.
The stupidity of docker is requiring unique IPv4 addresses even on
isolated (!) networks. This means we have to manually give each of our
test setups a different subnet, and then we can at least run one
instance that test in parallel to at most one instance of each other
test.
If this weird reestriction about unique IPv4 addresses didn't exist,
we could start any number of test runs in parallel.
