Bug 1894146: Limit the default number of API workers to 4

[dtantsur]

12 is a lot of workers. With up to 100MiB of RAM per each, ironic-api
processes may occupy more than 1GiB of RAM in such configuration.

Since even CERN uses 2 workers in their configuration, we should
be fine with no more than 4. A similar change is made upstream:
