Keystone as part of project delete invalidates the used tokens.

Invalidating the user tokens in memcache is taking long time ( will discuss with Sachin on this and get back)
I changed the token backend to sql in keystone.conf and restarted keystone.

[token]
#driver = keystone.token.persistence.backends.memcache.Token
driver = keystone.token.persistence.backends.sql.Token

Now the delete time is small.

Thanks,
Ignatious
