gcloud-sqlproxy - Helm Chart not compatible with cloud-sql-proxy >=2.0.0

[BapRx]

Hello, thank you for maintaining this helm chart, it is unfortunately not compatible with the cloud-sql-proxy images starting at the version 2.0.0.

The entrypoint of the container has changed from cloud_sql_proxy to cloud-sql-proxy and since it is not configurable via the values, we are stuck with containers <2.0.0.
This is the PR which introduced the change: GoogleCloudPlatform/cloud-sql-proxy#1326

Note that the container registry has changed at the same time: gcr.io/cloudsql-docker/gce-proxy -> gcr.io/cloud-sql-connectors/cloud-sql-proxy (cf GoogleCloudPlatform/cloud-sql-proxy#1607 (comment))
