Add support for Google Cloud SQL Query Insights

[ve6yeq]

Recently, a new feature Query Insights was added to Google Cloud SQL for PostgreSQL. This is enabled with the following new keys on the SQLInstance resource:

apiVersion: sql.cnrm.cloud.google.com/v1beta1
kind: SQLInstance
settings:
    insightsConfig:
      queryInsightsEnabled: true
      queryStringLength: 1024
      recordApplicationTags: true
      recordClientAddress: true

As there is strict checking of allowed keys, the following patch needs to be applied:

diff --git a/crds/sql_v1beta1_sqlinstance.yaml b/crds/sql_v1beta1_sqlinstance.yaml
index c20c085..24cc9c3 100644

Hi @ve6yeq, thanks for making the enhancement request.

Since Config Connector uses terraform provider under the hood, these fields should be added into Terraform first. Then our pipeline will introduce those fields on the next version.

Here is the Terraform feature request to track - hashicorp/terraform-provider-google#8328
