There was a period where we didn't generate unencrypted SSL certs
for nonlocal users; create them now (and generally create any
missing unencrypted/encrypted cert for active users).

Also, now renew certs for nonlocal users.

same as 503 error code.

physical type on shared nodes so that the limits do not apply to
them (on the physical type).

1. Show the reason on the listing page, as popover in the last
   column. Makes it easier to approve directly from the listing page if
   you can see the reason.

2. Add optional approval message to pass along to the user.

Aka, add some locking, stupid!

1. Do not mark down nodes as needing to be updated, they just get stuck
   there.

2. In the CM daemon, what for slivers/aggregates that have been stuck in
   updating users for too long, and cancel the update. Typically this is
   cause a node is wedged or not participating (CORD), so again just
   cancel and reset the state.

knows to tell the user something useful.

ifaces that correspond to endpoints on nodes. Makes it easier to
do something like this, if we init the interfaces on the nodes with IP
and mask and bring it up.

	# Add a raw PC to the request and give it an interface.
	node1 = request.RawPC("node1")
	iface1 = node1.addInterface()

	# Specify the IPv4 address
	iface1.addAddress(pg.IPv4Address("192.168.1.1", "255.255.255.0"))

	# Add another raw PC to the request and give it an interface.
	node2 = request.RawPC("node2")
	iface2 = node2.addInterface()

	# Specify the IPv4 address
	iface2.addAddress(pg.IPv4Address("192.168.1.2", "255.255.255.0"))

	# Add L1 link from node1 to node2
	link1 = request.L1Link("link1")
	link1.addInterface(iface1)
	link1.addInterface(iface2)

Emulab Docker CMD and Entrypoint to runit services

See merge request emulab/emulab-devel!34

need to watch for group names longer then FreeBSD max, and convert to
unix_gid, and easier to fix the caller code if I do that in one place.

This adds to the preparation of Docker images running
on the Emulab system by creating a new runit service
handling the details of their CMD and Entrypoint capabilities.
This scripting also sets the scaffolding for custom
CMDs and environment variables to be set by the user
as a part of their profile parameters.
