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.

4d967dd17a hydra-eval-jobs: Pass all inputs as 'inputs' arg. 
If there is no input named 'inputs', hydra-eval-jobs now passes in a set
of lists, where each attribute corresponds to an input defined in the
jobset specification and each list element is a different input alt, as
an argument named 'inputs'.

Among other things, this allows for generic hydra expressions to be
shared amongst projects with similar structures but different sets of
specific inputs.

4d26546d3c Add support for tracking custom metrics 
Builds can now emit metrics that Hydra will store in its database and
render as time series via flot charts. Typical applications are to
keep track of performance indicators, coverage percentages, artifact
sizes, and so on.

For example, a coverage build can emit the coverage percentage as
follows:

  echo "lineCoverage $pct %" > $out/nix-support/hydra-metrics

Graphs of all metrics for a job can be seen at

  http://.../job/<project>/<jobset>/<job>#tabs-charts

Specific metrics are also visible at

  http://.../job/<project>/<jobset>/<job>/metric/<metric>

The latter URL also allows getting the data in JSON format (e.g. via
"curl -H 'Accept: application/json'").

common.tt: Properly generate URL for /api/scmdiff. 
If Hydra isn't hosted on https://example.com/ but something like
https://example.com/hydra/, the URL for /api/scmdiff would have ended up
on /api/scmdiff rather than /hydra/api/scmdiff.

This is because we didn't use the URI resolver from the controller,
hence we're using it now to build up the whole URL including the query
string.

5919e911db Don't show how long a machine has been idle 
Without an index on (machine, stoptime desc), this requires a
sequential scan. And adding a whole index for this seems
overkill. (Possibly the queue runner could maintain this info more
efficiently.)

35b7c4f82b Allow only 1 thread to send a closure to a given machine at the same time 
This prevents a race where multiple threads see that machine X is
missing path P, and start sending it concurrently. Nix handles this
correctly, but it's still wasteful (especially for the case where P ==
GHC).

A more refined scheme would be to have per machine, per path locks.

2ece42b2b9 Support preferLocalBuild 
Derivations with "preferLocalBuild = true" can now be executed on
specific machines (typically localhost) by setting the mandary system
features field to include "local". For example:

  localhost x86_64-linux,i686-linux - 10 100 - local

says that "localhost" can *only* do builds with "preferLocalBuild =
true". The speed factor of 100 will make the machine almost always win
over other machines.

008d610467 getQueuedBuilds(): Don't catch errors while loading a build from the queue 
Otherwise we never recover from reset daemon connections, e.g.

  hydra-queue-runner[16106]: while loading build 599369: cannot start daemon worker: reading from file: Connection reset by peer
  hydra-queue-runner[16106]: while loading build 599236: writing to file: Broken pipe
  ...

The error is now handled queueMonitor(), causing the next call to
queueMonitorLoop() to create a new connection.
