Set upload_image policy to control data upload

There was no policy to control data upload.
Up until today, the add_image policy was a all or nothing, from metadata
to the actual data. Now, with the combination of add_image and upload_image
an administrator will have finer control over the whole chain.

Glance image-list failed when image number exceed DEFAULT_PAGE_SIZE

The root cause of the problem is that DB2 does not allow
an empty string ('') for datetime field. So we set the
default value of datetime as None.

Remove TestRegistryDB dependency on TestRegistryAPI

TestRegistryDB does not set up the sqlalchemy db it uses with the db models.
These tests only pass when run in conjunction with TestRegistryAPI because that
test case does set up the db. TestRegistryDB should set up the DB as it needs
to.

Move is_image_sharable to registry api

When using the membership kwarg in is_image_sharable with the sqlalchemy driver,
an AttributeError may be raised since the 'member' variable is not always
defined. This function was copied throughout the db drivers and untested.

This patch adds tests and moves the function to the v1 registry api, where it
was the only place being used. Tests for this function in test_context were
removed as it does not make sense to test this function there and allowed for
the removal of the membership kwarg.

Makes tasks owner not nullable in models.py

The tasks table scheme in migration for adding tasks to Glance DB has a
flag for disabling from setting a NULL owner.

In order to keep the behavior consistent across the glance codebase,
this patch adds owner as not nullable in the models.py.

Refactor StorageQuotaFull test cases in test_quota

There were two test cases in test_quota that shared the same name, but
did almost the same thing. After a bit of digging, it looked like most
of the test cases did the almost same thing, so I refactored the common
bits and fixed the test case name duplication.
