when deploying SS with SS ss-* deployment commands pick up the client libs from site-packages

[konstan]

When deploying SS with SS ss-* deployment commands pick up the client libs from site-packages, and may fail when changes are made to slipstream-client on master, while the deployment from SS (e.g. Nuvla) provides different version of SS client. This leads to the need of forcing the SS client to first be search under /opt/slipstream/client/lib/.
