Description of PR

Summary:
Fixes # (issue)

The pytest-ansible plugin always assumes that the value
of cli argument '--inventory' is a single inventory file.
With this enhancement, we can pass in multiple inventory
files using the cli argument '--inventory'. The multiple
inventory files can be separated by comma ','.

For example:
pytest --inventory "inventory1, inventory2"
pytest --inventory inventory1,inventory2

Run test scripts that depends on multiple inventory files by specifying multiple inventory files from command line:

py.test --inventory "../ansible/veos, ../ansible/inventory" --host-pattern all --testbed example_testbed_t0 --testbed_file ../ansible/testbed.csv --show-capture no --log-cli-level debug test_nbr_health.py

Any platform specific information?
