Adds option to select a different subnet when adding 'vip'

With this fix, 'AddVip' from the dashboard gives user an
option to select a different subnet than the 'pool' subnet
and then creates a 'vip' with an ip (provided/next available)
from the selected subnet.

Breakdown CSS: split out the resource browser

Now that everything has been converted to scss, splitting out the
individual components of our CSS can and should begin!

In an effort to do small changes (to keep them mergable and reviewable)
I'm only splitting out the resource browser stuff.  I'm trying to
balance the style that Maxime has used throughout the previous reviews
relating to this blueprint while also not changing everything that can
be changed.

Add create and update times for trove components

Currently trove doesn't show created and updated
timestamps on databases and backups - this is
inconsistent with other dashboard components such
as compute and images

Add created and updated timestamps to details
page of databases and backups.
Backups was already display a 'Created At'
timestamp so also made the wording and formatting
of this consistent
