As of today, we have two patterns: one for the path (pattern) and another one for the host (hostname_pattern).

In #3378, it was suggested to rename pattern to path and hostname_pattern to hostname.

That's fine by me, but of course, we will keep pattern support even after the LTS release (which should not be a problem). The documentation for 2.2 will of course only use the new name.

What others think?
