Add all providers to TsscPlatform CRD

[andykrohg]

• Add all providers (ploigos services) to the TsscPlatform CRD
  • This allows us to omit CodeReady Workspaces and Mattermost by default, since they aren't required to directly support the pipeline.
  • I supplied default/required values in the CRD as well:

    apiVersion: redhatgov.io/v1alpha1
    kind: TsscPlatform
    metadata:
    name: tsscplatform-jenkins
    spec:
    tsscPlatform:
    services:
      continuousIntegration:
        name: jenkins
        managed: true
      sourceControl:
        name: gitea
        managed: true
      artifactRepository:
        name: nexus
        managed: true
      staticCodeAnalysis:
        name: sonarqube
        managed: true
      continuousDeployment:
        name: argocd
        managed: true
      uat:
        name: selenium
        managed: true
      containerRegistry:
        name: nexus
        managed: true

• Reorganize deployment/configuration directories in roles/tssc-platform for better code reutilization
