Console UI - Support for mounting roleMapping and GitHooks

As a Console UI user I want to optionally define the name of an existing Secret, ConfigMap or PersistentVolumeClaim to use for mounting gitHooks and a Secret or ConfigMap to use for mounting the roleMapping file.
These fields will be displayed together with the existing githooks and rolemapping properties

GitHooks

This only affects the console part for decisioncentral and businesscentral, not businesscentral-monitoring. That is, the following environments:

• RHDM/RHPAM trial, authoring and authoringHA

The expected layout should be under the Console subPage, after Replicas field
Add a group for GitHooks with:

• Mount path optional string
• From with two fields
  • Kind: dropdown with empty, ConfigMap, Secret, PersistentVolumeClaim
  • Name: String
    If Kind is not empty name is mandatory

RoleMapper

The roleMapper property under the auth subPage already exist. The new values to add are after the replaceRoles property.

• From with two fields
  • Kind: dropdown with empty, ConfigMap, Secret
  • Name: String
    If Kind is not empty name is mandatory
