    Adding user_id handling to keypair index, show and create api calls

    Administering an openstack cluster I found the need to see what keypairs a
    user had. I found this bug that was requesting the same thing and decided
    to implement it. This is the update to the api server to handle a query
    param passed to return a keypair list for a specific user-id. Only a user
    with admin privileges is allowed to make this call.

    Allowing the administrators to be able to list and get details of keypairs
    which owned by users other than themselves, as well as creating new and
    deleting keypairs on behalf of their users.

    DocImpact: This adds API microversion
    Implements blueprint admin-query-any-keypair
    APIImpact
    UpgradeImpact: Policy rules of the index, create, delete and show
                   operations has been updated to support the change.
