Run tests with coverage on CI (#2141)

Combine 'make cover' and 'make acc-cover' into single command. They
still write coverage into different files -- it would be useful to see
separate coverage numbers.

Note, we're not making use of coverage information yet. However, running
tests in CI with coverage will
- let us catch issues that only manifest when coverage is enabled, like
https://github.com/databricks/cli/pull/2150
- will let us know if there are any issues with running coverage on CI
before investing in additional coverage support
