Standby mode metric

[rmontenegroo]

Hi!

I just added the host standbyMode metric. Not a big change at all.

@rmontenegroo Hello and Thank you for the PR! This all looks good but is there any way we could get a test for this metric?

Sure! Trying to follow your CI script test. Using python 3.6.9 here but I got

(python3.6) rodmonte@deadpool:~/develop/vmware_exporter$ pytest --cov=. -v tests/unit
Traceback (most recent call last):
  File "/home/rodmonte/develop/python3.6/bin/pytest", line 5, in <module>

    params = attr.ib(convert=attr.converters.optional(tuple))
TypeError: attrib() got an unexpected keyword argument 'convert'

right after pip installing requirements.
Any tip?
