Title: (maint) Clarify the merge-up process in COMMITTERS

Without this patch some of the committers are using a process that
involves merging a topic branch based on stable into both `stable` and
`master`. This is a problem because it's confusing and inconsistent
from other committers who are merging a topic branch into `stable`, then
merging `stable` into `master.

The two processes, while equivalent in nature, produce different and
inconsistent log messages when reviewing `git lg`. For example, the
following log is produced by the process that does not merge up:

* e130aa5 Merge branch 'maint/stable/filebucket_clarifications' 30 minutes ago Hailee Kenney (HEAD, origin/master, master)
|\
| * b301ada Maint: Improve documentation of filebucket attributes 33 minutes ago Nick Fagerlund

Compare this to the log of the stable branch and observe how there are two very
similar merge commits with the log `Merge branch
'maint/stable/filebucket_clarifications'` Please observe these similar commit
messages have different commit ID's, e130aa5 and 47fd6f9 respectively, and both
merge commits are bringing in the change contained in b301ada.

* 47fd6f9 Merge branch 'maint/stable/filebucket_clarifications' into stable 33 minutes ago Hailee Kenney (origin/stable, stable)
|\
| * b301ada Maint: Improve documentation of filebucket attributes 34 minutes ago Nick Fagerlund
|/
* edfabfd (packaging) Update PUPPETVERSION to 3.2.0-rc2 7 days ago Matthaus Owens (3.2.0-rc2)

Using the merge-up process made clear in this patch, the history will look as
follows:

* 1f79310 Merge branch 'stable' 5 seconds ago Jeff McCune (HEAD, master)
|\
| * c6f6ffb Merge branch 'fix/stable/clarify_merge_up' into stable 45 seconds ago Jeff McCune (stable)
| |\
| | * 44b999c (maint) Clarify the merge-up process in COMMITTERS 53 seconds ago Jeff McCune (fix/stable/clarify_merge_up)
| |/
* | e130aa5 Merge branch 'maint/stable/filebucket_clarifications' 35 minutes ago Hailee Kenney (origin/master)
|\ \
| | * 47fd6f9 Merge branch 'maint/stable/filebucket_clarifications' into stable 36 minutes ago Hailee Kenney (origin/stable)

This minor difference also has the effect of making `git branch --contains
c6f6ffb` much more useful, as both `master` and `stable` will contain merge
commits made into `stable`.
