   Rename requires files to standard names.

    Rename tools/pip-requires to requirements.txt and tools/test-requires
    to test-requirements.txt. These are standard files, and tools in the
    general world are growing intelligence about them.

that.

Disable eventlet monkey-patching of DNS

This change avoids eventlet's monkey-patching of DNS resolution.
eventlet's doesn't support IPv6, for example.

The way to avoid eventlet's DNS is to set an environment
variable. The trick is the environment variable needs to be set
before eventlet is imported.

A similar change was made in nova, so this is just copying that
code and technique to Keystone.

This allows re-enabling the IPv6 tests, too.

Revert "Set EVENTLET_NO_GREENDNS=yes in tox.ini."

We don't need this since EVENTLET_NO_GREENDNS=yes is set in
keystone.common.wsgi_server .

This reverts commit 46b224abf1c6f7c9bd579806f202a019e2695b29.

Improve the performance of tokens deletion for user

Provide new delete the tokens api 'delete_tokens' to support
delete all the tokens for user in one session in the sql backend. For
the kvs and memcache, I also provide the corresponding implementation.
