agent: initialise mongo admin user before initialising state

This allows us to open mongo fully authenticated when opening
state, thus allowing the use of session.Copy.
state: remove unit.SetMongoPassword
Only login to "admin" mongo database

We create a user in the admin database
with read/write privileges to all databases,
so there's no need to add users to each
other database. Consequently, we can remove
the mongo.SetMongoPassword function and
change state.Machine.SetMongoPassword to
just call mongo.SetAdminMongoPassword.

mongo.SetAdminMongoPassword no longer
calls Login itself.
agent: use mongo.DialWithInfo

This sets the socket timeout, etc.

Only login to "admin" mongo database

We create a user in the admin database with read/write privileges to all
databases, so there's no need to add users to each other database.
Consequently, we can remove the mongo.SetMongoPassword function and change
state.Machine.SetMongoPassword to just call mongo.SetAdminMongoPassword.

mongo.SetAdminMongoPassword no longer calls Login itself.

This is a reimplementation of PR #414, which was broken. Previously
SetAdminMongoPassword would call Login, which meant machine-0 would
login as machine-1, machine-2, etc. This would break when the other
machine came up and its agent changed the password for that user.

Also:
 - state: remove unit.SetMongoPassword
 - agent: initialise mongo admin user before initialising state

   This allows us to open mongo fully authenticated when opening
   state, thus allowing the use of session.Copy.
Various changes to support Mongo 2.6

Disable auth in Mongo for all except
a handful of tests, which we segregate
and enable authentication for explicitly.

Merge pull request #490 from tasdomas/factory-followup-fixes

Remove varargs and test context object from factory.

Due to lifetime differences, it is impractical and not recommended to set the test context for the factory during initialization, so all creation methods (MakeUser, MakeService, etc.) now take an additional *gc.C parameter.

Also, variadic parameters are exchanged for a pointer parameter for object properties - MakeUser() becomes MakeUser(c, nil). This makes the code more readable and idiomatic.
Added support for a metrics collections

insert a batch of metrics instead of one at a time

only allow metrics to be added if the unit is alive
use right version of charm as per master
Merge pull request #466 from mattyw/add-metric-collection-to-state

Added support for a metrics collections

Added a metric collection for storing unit metric in the state server

Only support for:

* adding new metrics
* getting lists of unsent metrics
* setting the sent flag
action-set: a jujuc command for Actions to send values back to state

action-set permits action hooks to define an arbitrary map of params
which will be returned to the state server at the end of the Action.
action-set multiple invocation tests and panics fixed
action-set: a jujuc command for Actions to send values back to state

Addressed fwereade's concerns for PR 415.
