Changes to support the migration to a GCP database.
Modified the application context to use a new connection pool and include the SSL connection parameters. All connection configuration is now in the context file.
Modified the one class that uses the database connection object. Removed configuration parameters and changed the object type to a generic DataSource type.
Updated pom.xml with some minor library version updates per recommendation from Dependabot.
