Add pre_clone_script setting to helm chart
The current helm chart for gitlab-runner does not allow for adding configuration options to the config.toml.
For example, we have a need to add a "pre_clone_script" such as: config.toml: ... pre_clone_script="umask 0022"
Workaround
Define RUNNER_PRE_CLONE_SCRIPT
inside of envVars
envVars:
- name: RUNNER_PRE_CLONE_SCRIPT
value: "umask 0022"
