Replacement `_` on `_LE` in all LOG.error

oslo.i18n uses different marker functions to separate the
translatable messages into different catalogs, which the translation
teams can prioritize translating. For details, please refer to:
http://docs.openstack.org/developer/oslo.i18n/guidelines.html#guidelines-for-use-in-openstack

There were not marker fuctions some places in directory network.
This commit makes changes:
* Add missing marker functions
* Use ',' instead of '%' while adding variables to log messages

Nova should be in charge of its log defaults

Oslo's log module has a set_defaults which Nova can use
to set the context logging format and default log levels.
We should not have to fix default levels in oslo and then
sync across to Nova. This becomes all the more important
when we move to oslo.log library so we should get started
now

Set logging level for glanceclient to WARN

When capturing a snapshot for example, glanceclient logs
the whole uploaded image into the nova compute logs as
glanceclient's log level is set to DEBUG by default

Remove project id in ViewBuilder alternate link

Clearly nobody really uses the "application/vnd.openstack.image"
links in the returned results from GET /v2/{tenant}/images
REST API call, since the link URI returned in it is wrong.

Glance URIs do *not* contain a project or tenant in the URI
structure like Nova's REST API URIs do, but _get_alternate_link()
method of the image ViewBuilder tacks it on improperly:

Add API schema for v2.1 "resize a server" API

Some v2.1 APIs(create/update/rebuild server) contains the API
extension feature, it searches extension methods with its method
name and operates them automatically.

It is necessary to change the API schemas also automatically based
on the API extension loading condition, because the API extensions
add API parameters.

This patch adds API schema extensions which are implemented with
the same mechanism (stevedore library) as the API extension for "resize
a server" extensions.

Partially implements blueprint v2-on-v3-api
