Added a Powershell script which automates the deployment of SQL Server 2019 related resources using the default manifest files. The script performs the following actions

1. Creates a namespace named ag1 (can be overwritten while calling the script to create a different namespace in future, this would require the removal of the hardcoded value of ag1 namespace from the sample manifest files)
2. Deploys SQL Server operator using the operator.yaml file
3. Creates sapassword and masterkepassword
4. Deploys SQL Server 2019 custom resources defined in the sqlserver.yaml file
5. Deploys Availability Group services defined in the agservices.yaml file

The script can be executed from sample-deployment-powershell-script directory as

.\deploy-ag.ps1

We don't have AG operator anymore for SQL2019. So I am closing this pull request.
