Allow overriding the log level for ironicclient

oslo provides a 'default_log_levels' conf variable for overriding
logging levels for certain modules. This could be used to override
ironicclient's default logging level, however it requires re-setting
all of the log levels for oslo's defaults. This is rather inconvenient.

I think it makes sense to allow the ironic virt driver to have an easy
config option for this. When in debug mode, ironicclient logs every
single API call and response. In an environment with a lot of nodes,
it clutters the logs.

This adds a 'client_log_level' config option to the 'ironic' config
section in nova. If it's unset (default), there's no change in behavior.
If it's set, it takes precedence over the 'default_log_levels',
'verbose', and 'debug' settings that one may have in nova.conf

Example usage:
[ironic]
client_log_level=INFO

Prevent updating UUID of Node, Port and Chassis on DB API level

UUID is seen as something similar to pkey and is not expected
to be updated after creation.
This patch makes update_{node,chassis,port} raise InvalidParameterValue,
if 'uuid' field is passed in.

Document 'POST /v1/.../vendor_passthru'

http://docs.openstack.org/developer/ironic/webapi/v1.html does
not contain anything about how to use vendor passthru endpoints.
This adds 'POST /v1/nodes/(node_uuid)/vendor_passthru' and
'POST /v1/drivers/(driver_name)/vendor_passthru' to that
html page.

Update docstring for api...node.validate

Add the param to the docstring for api.controllers.v1.node.validate.
With this change, the generated webapi page [1] will include this
information. Without it, it shows:
    Validate the driver interfaces. :type node_uuid: uuid

Fix node to chassis and port to node association

This patch is fixing the Ironic API to allow "replace" (or "add" that
acts like a replace on an existing field) the chassis_uuid field from
nodes and the node_uuid field from ports.
