    Remove oslo.serialization from requirements.txt

    Change I00f66b0f3c8e9f688429ee78bd51608a4dcac140 added
    oslo.serialization to requirements.txt on stable to unwedge the gate due
    to keystone on stable testing against master level keystoneclient which
    required oslo.serialization.

    Later, change I079fa77501b8987a4724d03a792b084a6d853e21 fixed the
    testing problem by running the tests in a venv, so we can just
    remove oslo.serialization from keystone's requirements.txt now.
