Eelco Dolstra 7e954aff03 Keep machine stats even when a machine is removed from the machines file 
This is important for the Hydra provisioner, since it needs to be able
to see whether a disabled machine still has jobs running on it.

Eelco Dolstra 092d60735b Keep track of wait time per system type 
I.e., how much time the currently runnable steps per system type have
been waiting. This is useful for deciding whether to provision more
machines.

Eelco Dolstra ea1eb2e3fb Keep track of requiredSystemFeatures in the machine stats 
For example, steps that require the "kvm" feature may require a
different kind of machine to be provisioned. This can also be used to
require performance-sensitive tests to run on a particular kind of
machine, e.g., by setting requiredSystemFeatures to something like
"ec2-i2.8xlarge".

Eelco Dolstra d571e44b86 Keep stats for the Hydra auto scaler 
"hydra-queue-runner --status" now prints how many runnable and running
build steps exist for each machine type. This allows additional
machines to be provisioned based on the Hydra load.

Eelco Dolstra 97f11baa8d Revive jobset scheduling 
(I.e. taking the jobset scheduling share into account.)

Eelco Dolstra eb13007fe6 Allow build to be bumped to the front of the queue via the web interface 
Builds now have a "Bump up" action. This will cause the queue runner
to prioritise the steps of the build above all other steps.
