Add feature
Several changes
- Use GitLab variables to set ssh info (SSH_KEY, SSH_USER, SSH_HOST)
- Use TOML file rather than hard-coded config to separate vanilla and e3
- Now the tests can also run with a already running IOC
- Add more test functions
- Increase event interval limit from 1.0e-06 to 2.0e-06 (sometimes the interval limit is ~1.5e-06) see #427989
