more detailed version information

After installing all three packages from their respective latest heads of master, I get the following version informations:

>>> import bilby
>>> bilby.__version__
'1.0.0: (CLEAN) 3c93842c 2020-08-21 07:19:46 -0500'
>>> import bilby_pipe
>>> bilby_pipe.__version__
'1.0.0'
>>> import parallel_bilby
>>> parallel_bilby.__version__
'0.1.4: (CLEAN) 0703664 2020-08-10 17:57:28 -0500'

It would be nice to bring the bilby_pipe output to the same level of detail (including hash, state and date) as the other two packages.
