config: rename `revlog` section into `storage`

The idea was suggested by Gregory Szorc on IRC. It is more generic and seems
better. It is probably best to rename the section before it ever makes into an
official (non-rc) release.

The only config option currently in this section have been prefixed with
`revlog` to clarify it applies to `revlog` related storage.

-``optimize-delta-parent-choice``
+``revlog.optimize-delta-parent-choice``
     When storing a merge revision, both parents will be equally considered as
     a possible delta base. This results in better delta selection and improved
     revlog compression. This option is enabled by default.
