Add the option in values.yml to specify usergroups and permissions in SonarQube

Example values.yml:

rbac:
  enabled: true
  all_global_permissions: ["admin", "profileadmin", "gateadmin", "scan", "provisioning"]
  all_project_permissions: ["admin", "codeviewer", "issueadmin", "securityhotspotadmin", "scan", "user"]
  user_groups:
    - name: "test-administrators"
      global_permissions: ["admin", "profileadmin", "gateadmin", "scan", "provisioning"]
      project_permissions: ["user", "codeviewer", "scan", "admin", "issueadmin", "securityhotspotadmin"]
    - name: "test-developers"
      global_permissions: ["gateadmin", "scan"]
      project_permissions: ["user", "codeviewer"]

This should:

• create user groups test-administrators and test-developers
• User group test-administrators should have global permissions "admin", "profileadmin", "gateadmin", "scan", "provisioning" and project permissions "user", "codeviewer", "scan", "admin", "issueadmin", "securityhotspotadmin"
• User group test-developers should have global permissions "gateadmin", "scan" and project_permissions "user", "codeviewer"
• any global permissions in all_global_permissions that are not listed in the user group global permissions should be removed from the user group
• any project permissions in all_project_permissions that are not listed in the user group project permissions should be removed from the user group

Add the option in values.yml to specify license key to activate Developer Edition

Example values.yml:

license:
  key:

This should:

• Install the license key specified if Developer Edition of SonarQube is deployed

Add the option in values.yml to configure ALM integration with a given GitLab instance

Example values.yml:

alm:
  gitlab:
    key: mygitlab
    personalAccessToken: 1234
    url:  https://mygitlab/api/v4

This should:

• Create a integration called mygitlab and configure the specified url and PAT
