[osci] Ci job for 6.0-updates uses keystone-client from master branch

[Alexey Khivin]

gate-keystone-python27-updates for 6.0-updates uses keystone-client from upstream which is not compatible with MOS60 and juno keystone

Job should use client from requirements.txt not from upstream github

It looks like git clone and downloading last upstream version is executed inside unit test, it is not error in CI scripts.
