1. Proposed title of this feature request

Support multiple project templates

2. What is the nature and description of the request?
To have the ability to inject multiple project templates (https://docs.redhat.com/en/documentation/openshift_container_platform/4.16/html-single/building_applications/index#modifying-template-for-new-projects_configuring-project-creation) and make them usable from YAML manifests as well as CLI. The behavior shall be similar to how storageclasses behave, i.e. you will have a default template and can select a different one if you have sufficient permissions to do so.
Some examples are:
```
oc new-project --template=platform-admin
oc new-project --template=developer

oc -n openshift-config get template
NAME DESCRIPTION PARAMETERS OBJECTS
developer (default) 5 (5 blank) 4
platform-admin 5 (5 blank) 4

oc -n openshift-config get template developer -oyaml
apiVersion: template.openshift.io/v1
kind: Template
metadata:
name: developer
objects:
<...>

oc -n openshift-config get template platform-admin -oyaml
apiVersion: template.openshift.io/v1
kind: Template
metadata:
name: platform-admin
objects:
<...>
```

To use it from a YAML manifest template, you shall either be able to use a label or a dedicated resource parameter in a Project
```
apiVersion: project.openshift.io/v1
kind: Project
metadata:
name: my-developer-project
labels:
projectTemplate: developer
—
apiVersion: project.openshift.io/v1
kind: Project
metadata:
name: my-developer-project
projectTemplate: developer
```

Similar is true for a ProjectRequest
```
apiVersion: project.openshift.io/v1
kind: ProjectRequest
metadata:
name: my-developer-project
labels:
projectTemplate: developer
description: '${NAMESPACE_DESCRIPTION}'
displayName: '${NAMESPACE_DISPLAY_NAME}'
—
apiVersion: project.openshift.io/v1
kind: ProjectRequest
metadata:
name: my-developer-project
description: '${NAMESPACE_DESCRIPTION}'
displayName: '${NAMESPACE_DISPLAY_NAME}'
projectTemplate: developer
```
3. Why does the customer need this? (List the business requirements here)
