Standardize bashate and add linters

The linters gate combindes pep8 and bashate (and then any other
linters we want). This changes bashate to be a sript rather than doing
a script inline. This matches the way other projects (and
project-config themselves) uses bashate [1].

Once a change upstream merges we can remove the redundant pep8 and
bashate gates.
