Blazar doesn't populate lease user_id

[Pierre Riteau]

Blazar creates leases with the user_id field in the database set to NULL. This results in user_id being displayed as blank in CLI output.

    Set user_id when creating leases

    The user_id field in leases is set from ctx.user_id, which is always
    None because it is not defined in trusts.create_ctx_from_trust().
    Nevertheless, we cannot use this value since we are in the trustee
    context, which is the blazar user.

    This patch modifies the API handler so that the real user_id is included
    in the lease_values dict passed to create_lease(). Ideally, the context
    would be extended to include a field referring to the trustor user.
