Nikhil Komawar cc869ec7bb Complete and update Newton release notes
* This commit updates any formatting, grammatical or other issues
    in the release notes for Newton
  * It also adds any missing yet important release notes to be part of
    the release

Also, this commit standardizes release note page ordering:

  * In order to support automatically updating the release notes when we
    create stable branches, we want the pages to be in a standard order.
    This patch updates the order to be reverse chronological, so the
    most recent notes appear at the top. ( Inspired by Change

- Improved configuration option descriptions and handling.

The glance configuration options have been improved with
detailed help texts, defaults for sample configuration
files, explicit choices of values for operators to
choose from, and a strict range defined with ``min`` and
``max`` boundaries.
* It must be noted that the configuration options that
take integer values now have a strict range defined
with ``min`` and/or ``max`` boundaries where
appropriate.
* This renders the configuration options incapable of
taking certain values that may have been accepted
before but were actually invalid.
* For example, configuration options specifying counts,
where a negative value was undefined, would have still
accepted the supplied negative value. Such options
will no longer accept negative values.
* Options where a negative value was previously defined
(for example, -1 to mean unlimited) will remain
unaffected by this change.
* Values which do not comply with the new restrictions
will prevent the service from starting. The logs will
contain a message indicating the problematic
configuration option and the reason why the supplied
value has been rejected.
