- Remove the `tacker.agent` package. Its only module,
agent/linux/utils.py, is not referenced anywhere in tacker.
- Remove `subprocess_popen()` from `tacker.common.utils`; the removed
agent module was its only caller. The `subprocess` import it needed
goes away with it.
- Import `sleep()` used by the cooperative readers directly from the
time module instead of the eventlet fallback. `time.sleep(0)` yields
the GIL, so the readers still allow other threads to be scheduled
between chunks.
- Remove the GreenPool instantiated but never used by NfvoPlugin.
