This is really, really ugly.  So, keystone and nova don't offer us a way to
upload keypairs on behalf of another user.  Recall, we're using the adminapi
account to do all this setup, because we don't know the admin password.  So,
the below code adds all the keys as 'adminapi', then we dump the sql, do some
sed magic on it to get rid of the primary key and change the user_id to the
real admin user_id, then we insert those rows, then we cleanup the lint.  By
doing it this way, we eliminate our dependency on the SQL format and column
names and semantics.  We make two assumptions: 1) that there is only one field
that has integer values, and 2) the only field that is an exception to #1 is
called 'deleted' and we just set those all to 0 after we jack the whacked sql
in.  Ugh, it's worse than I hoped, but whatever.

This is one of the sickest one-liners I've ever come up with, but it
works like a charm!
