test for multiple rel order

615. By Kapil Thangavelu on 2013-02-14

disambiguate multiple relations at startup, use rel creation order, which naturally implies peers first.

Increase zk session and ping times.

During scale testing work, one of the take aways was the default zookeeper
session time was too low, which caused issues for any transient communication
problems between the agents the zk. The managed client work landed subsequently
does recovery for this and for session expiration, but its better to avoid
the issue entirely by increasing the session time and increasing the heartbeat
time periodicity.

Drop orchestra provider support

The orchestra provider is dead upstream, and represents
a significant support burden on the code base. Given
hardware deployments are directed towards MaaS and no
current users, its better to drop this now.

Fix relation-ids cache coherency for hooks.

Relation-ids was answering questions about relations
directly from state, whilst other pieces of relation-*
cli was using a hook execution cache. This led to
odd races where a hook would query relation-ids
and then attempt to use relation-list/etc against
that relation resulting in a relation not found error.

This branch also does a drive by to improve the error
reporting for relation not found to include the relation
id where applicable.

[trivial] serialized execution test propogation

Serialized unit execution on a machine/container

To prevent races for system resources like apt between different
units running on the same machine/container a shared file lock is
taken out for hook execution. Mechanism is resistant to dead
processes holding lock, however per previous juju behavior no
timeout is provided for maximum hook execution time.
