[JIRA] (OVIRT-2162) docs: Only explain how to run OST inside mock

docs: Only explain how to run OST inside mock --------------------------------------------- Key: OVIRT-2162 URL: https://ovirt-jira.atlassian.net/browse/OVIRT-2162 Project: oVirt - virtualization made easy Issue Type: Bug Components: OST Reporter: Gal Ben Haim Assignee: infra We prefer to use mock when running OST, because then we can install the engine SDK from the internal repo (inside mock we use the root user). Currently, the docs contains an explanation on how to run with/without mock, which makes the docs complicated.
