[JIRA] (OVIRT-1920) Modify ci_env_client.py to be case and signs insensitive

Modify ci_env_client.py to be case and signs insensitive -------------------------------------------------------- Key: OVIRT-1920 URL: https://ovirt-jira.atlassian.net/browse/OVIRT-1920 Project: oVirt - virtualization made easy Issue Type: Task Components: mock_runner Reporter: Daniel Belenky Assignee: infra In OVIRT-1892 we make stdci config be case and signs insensitive. It means that when we will write a runner (or modify mock_runner) to use the new config, ci_env_client will have to deal with a normalized structure (without cases nor signs as dots and dashes).
