chore: rename flag to disable template insights (#21329)

Because this affects more than just the template insights
page (specifically it also affects the deployment stats endpoint which
is shown on bottom bar and Prometheus), the group is being renamed
generically to just "stats collection".  In the future if we need to
affect the other stats we can put those options here.

Then, because this change only affects a portion of stats, specifically
usage stats like connection and application time, bytes sent, etc, add a
new sub-group called "usage stats".

Then finally add back the "enable" flag.  This also gives us a place to
one day place an "anonymize" flag if we need to go that route.
