Prefer my personal E-mail address
The E-mail provider used by the openstack.org domain rejects
messages failing DMARC checks, including many posts to popular
mailing lists such as those on lists.openstack.org and the
oss-security mailing list. Since I need to maintain subscriptions to
any lists on which I'll post advisories to keep myself whitelisted,
I'm going to switch to using the personal E-mail address I use for
all my other OpenStack-facing work (so that the contact address
published here for me remains consistent with the one I'm using to
author and send advisories going forward).
The OpenPGP key listed for me here already had a UID for this
address, so no change to the key is needed.
