Azure: Run Lint task as separate job

Lint task uses PyPI to get the latest Pylint, which may pull in
any other packages as dependencies. For distro isolation the Lint
job should not produce any meaningful artifacts or they should not
be used in subsequent jobs. So, this job have to be isolated from
the others.
