debugindex: introduce a concept of "verbose-only" column

We are about to add a bunch of new column and most of them are probably only
relevant to --verbose.

We add some more testing of the `--verbose` mode in a sidedata context.

Test file dedicated to checking side-data related behavior

Check data can be written/read from sidedata

Check upgrade behavior
======================

Right now, sidedata has not upgrade support

Check that we can upgrade to sidedata
-------------------------------------

  $ hg init up-no-side-data --config experimental.revlogv2=no
  $ hg debugformat -v -R up-no-side-data | egrep 'changelog-v2|revlog-v2'
  revlog-v2:           no     no      no
  changelog-v2:        no     no      no
  $ hg debugformat -v -R up-no-side-data --config experimental.revlogv2=enable-unstable-format-and-corrupt-my-data | egrep 'changelog-v2|revlog-v2'
  revlog-v2:           no    yes      no
  changelog-v2:        no     no      no
  $ hg debugupgraderepo -R up-no-side-data --config experimental.revlogv2=enable-unstable-format-and-corrupt-my-data > /dev/null

Check that we can downgrade from sidedata
