Add postgresql memory store

[kbeaugrand]

Motivation and Context

I would like to provide a production-grade PaaS solution to store the vector database.
It provides PostgreSQL database support for memory. We can now use Azure Database for PostgreSQL or CosmosDB for PostgreSQL.

Fixes #166

Description

I added configuration support for PostgreSQL. in the kernel initialization.
Furthermore I updated the deployment script to support this configuration.

Note: In the deployment scripts, I've added the SqlAdminPassword parameter, which must be supplied during provisioning. I intentionally named it without the PostgreSQL name, as I also worked on implementing SQL Server Memory store in the SK repository. This parameter could be used by both databases during deployment.

Contribution Checklist
