After commit 89e2fad8ef,
pep8/bandit/bashate tox envs have different dependencies than
the default tox env. If tox envs with different dependencies share
some common envdir, tox env will be recreated every time a different
tox env is specified. (For example, "tox -e cover" after "tox -e pep8"
recreates the tox env.)
To address it, this commit introduces a new common envdir for linters
(envdir = {toxworkdir}/lint). It also moves deependencies of bashate
and bandit envs to pep8 env to ensure these three tox envs have the
same dependencies.
Cleanups are also made in test-requirements and lower-constraints.
* astroid and isort can be dropped from test-requirements.txt
as pylint has proper version cappings for astroid and isort.
(These cappings are available in pylint 2.5 and later.)
* reno is a document dependency, so it is unnecessary in test-requirements.
* reno, astroid and isort are dropped from lower-constraints
as they are not installed in lower-constraints tests.
