[PATCH 05/20] test: Implement virConnect(Un)RegisterCloseCallback

[Marc Hartmayer <mhartmay@xxxxxxxxxxxxxxxxxx>]

Implement the hypervisor APIs virConnectRegisterCloseCallback and
virConnectUnregisterCloseCallbacks and mark this feature as supported
in testConnectSupportsFeature. This increases test test coverage of
the test suite as then the testConnectRegisterCloseCallback and
testConnectUnregisterCloseCallback (which are almost identical to the
implementations of the remote and vz driver) will be called by the
virsh tests.
