Adds script to create a release using Tekton

This adds a bash script to deploy new version of hub on a cluster
using Tekton Pipelines. This will create a git tag push it to
tektoncd/hub and install and run pipelines for hub which will push
images to quay.io/tekton-hub.

+# Release Script
+
+The Release script does the following tasks:
+- fetch the latest main branch
+- create and push a git tag by version provided from the user
+- create supporting configuration for hub on the cluster
+- create secret and roles for the Tekton Pipelines
+- install the pipeline which will deploy the hub on the clusters
+
+## Prerequisites
+
+- Kubernetes or OpenShift cluster with Tekton Pipelines installed
+- kubectl CLI
+- git CLI
+
+### User Prerequisites
+
+- Access to push images to `quay.io/tekton-hub`
+- Access to push git tag to `tektoncd/hub`
+
+## Before Running the Script
+
+- Enable Tekton Bundle in Pipelines
+- Check the last hub release version [here](https://github.com/tektoncd/hub/releases) and enter the next in the script to
+- If you are deploying hub on a clean cluster
+    - You will need GitHub OAuth. You can create one using the steps given [here](https://docs.github.com/en/developers/apps/creating-an-oauth-app). Use any url for creating OAuth, later you can change it once hub is deployed.
+
+
+## Running the Script
+
+This will deploy the hub in `tekton-hub` namespace and run the Tekton pipelines for it in the `tekton-hub-ci` namespace.
+
+Input asked by the script:
+- Target Release Version: This is the tag to be created and pushed to the repository. Check the last tag created and enter the next verion.
+- Deploying on Openshift? Enter (Y or n) depending on your cluster. If OpenShift is selected, it will configure adm policy for the service account.
+- If there are not existing hub configuration in `tekton-hub` namespace, the script will ask for 
+    - Database Configuration: Enter Database name, user and password for the db to be created
+    - GitHub OAuth Configuration: Enter the OAuth Configuration you have created.
+    - JWT Signing key: Enter any random key which will be used to sign User JWTs.
+    - Access and Refresh Expire Time: Enter the time the token should be expired in. Refresh Expire time must be greater than Access Expire time. You can input time as `1d` = 1 day, `15h` = 15 hours, `30m` = 30 minutes.
+    - Hub Config Raw URL: No need to change it unless you are not deploying hub from tektoncd/hub.
+NOTE: If you have already hub instance in tekton-hub namespace and the above configuration are already created using secrets and config maps, then the above step will be skipped.
+- Quay registry credentials: Enter your credentials to push images to the registry
+
+Once, that is done,the script will create all configuration and then install the pipeline and resources requires by it. And start the Pipeline.
