aggressivemergedelta: document rename and move to `revlog` section
The config does not follow our naming guideline and "Aggressive" is probably a
word to keep away from users.
The option does not truly fit in the `format` section. It can be turned on and
off for existing repository without much consequence regarding compatibility.
A new `revlog` option is created to control behavior related to revlog writing
and reading. We can see multiple other config options that could be migrated
there.
* format.maxchainlen
* experimental.mmapindexthreshold
* experimental.sparse-read.density-threshold (in an updated form)
* experimental.sparse-read.min-gap-size (in an updated form)
In addition, we can foresee at least a couple of sparse-revlog related option
coming too (to reduce delta chain length and increase snapshot reuse)
These two extra options might fit there too. Unless we want to create a
section dedicated to caches and performance.
* format.chunkcachesize
* format.manifestcachesize
For now, we only migrate `optimize-delta-parent-choice` since it is getting
out of experimental. It is too close to the release to move the other one. In
addition, we still lack proper the prioritization of alias that would help
renaming them without bad consequence for users.
(Not fully happy about the `revlog` name but could not find better).
