66cc137d04 Split http capacity between simple and load
- Simple will use 'available_cores' from response.
- Load will use 'cores' and 'relative_load'.

0af5cf703a Allow to configure capacity strategy
- HTTP strategy: mechanism to compute load from db host.
- Fixed strategy: hardcoded number of queries to run at the same time, via configuration.

3a57331a54 Delegate job scheduling
There is a host scheduler managing the host locking.

When it can acquire a lock over the host it will delegate
all the tasks related to that host to the same scheduler.

This scheduler will take care of how many jobs it will submit,
and in which order. It's also responsible for guaranteeing the
execution order per user.

Capacity planner dictates how many jobs can be run at the
same time in a given host. There are two simple strategies:

1. Infinity: it will attempt to run as many jobs as different users.
2. One: it will run just one job at the same time.

Missing things:
 - Handle lock renewal failures.
 - Fair scheduling for pending/waiting users.
 - Capacity based on real resources.

ac7bad43a5 Lock by host instead of host + user
- Host lock only released if there are no pending jobs.
- Will allow to schedule jobs by host.
