tests: split out ansible_tests requirements Also remove hard-coded Ansible version, the tests don't need it, nor does local testing most of the time 6 years ago			`paramiko==2.3.2 # Last 2.6-compat version.`
tests: import fork_histogram.py. 6 years ago			`hdrhistogram==0.6.1`
Split dev_requirements.txt up according to test mode. 6 years ago			`PyYAML==3.11; python_version < '2.7'`
tests: Update test coverage to Python 3.9 The Travis Linux distribution must be upgraded because the Trusty (Ubuntu 14.04) image does not have Python 3.9. Xenial (Ubuntu 16.04) is the earliest version that offers Python 3.9. I have not chosen a later release, in order to aid restoration of Python 2.4 - 2.6 tests. 4 years ago			`PyYAML==5.3.1; python_version >= '2.7' # Latest release (Jan 2021)`
