Fix migration with fkeys

Creation of fkeys doesn't work in sqlite, so we should do these
changes in another dialects.
Fix bug 1204823.

Also we can have a problem with data conflicted with declared ForeignKey.
We should dump "bad" data to another place, upgrade and create FK.
Downgrade method should restore dumped data.

Change resource.resource_metadata to text type

The existing resource.resource_metadata column size is 5k chars,
which is not enough for some large JSON metadata payload,
so change to as Text column to make sure store all JSON string
without truncating.

Ensure combination alarm evaluator can be loaded

Fixes bug 1237578

Previously combination alarms were always skipped as the evaluator
was missing from the loadable stevedore extensions.

Ensure combination alarms can be evaluated

Fixes bug 1237589

Previously the retrieval of state for the constituent alarms always
failed for combination alarms, due to an incorrect attribute of
ceilometerclient being used. As a result combination alarms could
never be successfully evaluated.

Now the correct pluralized attribute is used.

Avoid leaking admin-ness into threshold-oriented alarms

Fixes bug 1237567

Previously when an admin created a threshold-oriented alarm on
behalf of an non-admin identity, this had the effect of leaking
visibility onto statistics for resources that would not normally
be visible to the non-admin tenant.

Now we ensure that an additional implicit threshold rule query
constraint is added on the project ID of the non-admin indentity
that will ultimately own the alarm.

This is acheived by splitting the query validation from the
construction of the kwargs from the query. The addition of the
implicit query constraint to the threshold rule can then be
delayed to a later point in the dispatch path where the full
context of the alarm is known (so that we can check for the case
where the alarm is created by an admin on behalf of another tenant).

Avoid leaking admin-ness into combination alarms

Previously when an admin created a combination alarm on
behalf of an non-admin identity, this had the effect of leaking
visibility onto alarms that would not normally
be visible to the non-admin tenant.

Now we validate all alarm ids with the project ID of the non-admin
identity that will ultimately own the alarm instead of the project ID
of the API caller.

Add support for keystoneclient 0.4.0

Keystoneclient auth_middleware changed the way it parses the datetime
returned from the cache, breaking the Ceilometer unit tests. This patch
fixes the fake cache system that's used in unit test, so it works with
all keystoneclient versions.

This also update the sample configuration files to include the new
options provided by keystoneclient 0.4.0.

Change to Text column to make sure we store all detail.
