A few places in the documentation had mentioned 6.7 as the version to
upgrade from, when doing an upgrade to 7.0. While this is technically
possible, this commit will replace all those mentions to 6.8, as this is
the latest version with the latest bugfixes, deprecation checks and
ugprade assistant features - which should be the one used for upgrades.

Adds a note that restarting half-or-more of the master-eligible nodes means
you're no longer doing a rolling upgrade, and may need to upgrade all the
things before the cluster returns to health.
Command needs `?v` so user can see the column headers. Otherwise the instructions in the note about checking the init and relo columns don't make sense
Upgrading the Elastic Stack perfectly documents the process to
upgrade ES from 5 to 6 when internal indices are present. However,
the rolling upgrade docs do not mention anything about internal indices.
This adds a warning in the rolling upgrade procedure, highlighting that
internal indices should be upgraded before the rolling upgrade procedure
can be started.
Tweak the upgrade instructions for moving from pre-6.3-with-x-pack to
post-6.3-default distribution. Specifically, you have to remove the
x-pack plugin before upgrading because 6.4 doesn't understand how to
remove it.
Relates to #34307
Since we disable allocation using persistent settings, we should be consistent and remove
the setting from the persistent storage. Otherwise an accidental restart will lead for shards
not being allocated.
