is generated from a template and includes a pools directory. Pool
templates are globbed and added. Assertsions and documentation updated
accordingly.
- Added ping and status pages, tests are required.
- Validate config before restarting service (won't end up with a faulty
config and an offline service).

- Decided against file globbing config, would be convoluted for this
case.
- Decided to stick with Unix socket instead of TCP port (can't have them
both for the same pool).
- Flushing handlers and waiting for service to come online.
- Logging to syslog.
- Better assertions.
- Added test for changes.
- Updated TODO list (didn't have to set user as web server, comes
correct by default).

- Include OpenBSD 5.9 in supported OSes.
- Better assertions.

- Enable free Ansible strategy to allow each host to proceed as fast as it can to help speed up some plays.

- Caching the entire virtualenv in Travis CI has proven to cause issues, caching just pip's cache directory.

- Use privileged container instead of just adding the sys_admin capability (the latter has been shown to be cause unrelated issues).

- Remove mention of tests/requirements.yml from the Requirements section in the README, relevant only for testing.
