subtests.docker_cli: Add run_ipc test

ISSUE: https://github.com/autotest/autotest-docker/issues/371#issuecomment-61664433
BUGS: _TBD (There are couple of bugs I haven't yet filled in BZ, please reveiw it and in the mean time I'll add the links); due of one bug the `host_hcont_c1cont` test fails, other tests should pass._

This test utilizes the '--ipc' feature of docker and uses SysV shm
to share data between various setups (host and guests).

__NOTE__: I set the `no_iteration` to quite high number, you might need to decrease it on some older HW as the tests runs in parallel...
__NOTE2__: I'll implement the remaining `TODO:` tests as special tests later, this is only the basic functionality...
OK, I'll keep it here and add another note in there...
