Portal. Yep, about time we get rid of all the hardwired cruft.

aggregate pnode/vnode counts.

extensions, to show on the admin extend page.

of image files present.

Add uploader_path to communicate the path to use to write the file.
Set in create_image.

defaults to NULL since we did not require names prior to this, thus there
is no unique key defined.

This info is in the manifest, but want the numbers available for DB
queries.

Number of extension where days where granted, and total number of
days added for all extensions.

the stack for too long, need to get it done.

since the image_history table is not appropriate for theses.

Remove auto_incrementing idx altogether. Better to just use exptidx, pool_id as a composite primary key. Bah.

experiment_stats.

and rspec that are used. This is to support Parameterized Profiles, where
the rspec is generated from a geni-lib script and user defined parameters.

Add manifest to apt_instance_history; I was not storing the manifest cause
I figured we could just ask the backend cluster for it. Well, that is kinda
silly, so lets store it locally. I'll have to go back and grab the
manifests for the current history entries.

Add isaptkey to user_pubkeys so that we can mark the key that comes in from
the instantiate page. This lets us keep the Emulab keys for a user
independent of the APT key, so that APT users only deal with a single key
on that path, without messing up their Emulab keys.

public url of the sliver on the backend cluster. Displayed only
to admins on the status page, might change that later.

Update some comments and rename GetAllowedLeases to AllowedLeases.

Minor consistency updates.
