The Cloud SQL Proxy project recommends 2Gi for ram. This changes the default resource requirements to match.

The URL for the released image version 0.0.5 now will be:
cloud-sql-connectors/cloud-sql-operator/cloud-sql-proxy-operator:0.0.5

And the installer URL will now be:
https://storage.googleapis.com/cloud-sql-connectors/cloud-sql-proxy-operator/v0.0.5/install.sh

Adds quickstart instructions to the README. This tells the user how to follow the existing
Cloud SQL Quickstart on GKE guide, adding a few extra steps in the middle, to try out
the operator.

Add the operator version to the proxy's user agent, so that we can track how many people
are using the operator.

Fixes #67.

…ct. (#141)

Removes fields from the CRD and associated code that converts those fields into
configuration on the proxy container. I removed fields that were unused in existing code
(like FUSE), fields that were unnecessary for minimum viable use of the proxy (like
telemetry args), and fields related to unix sockets, since that connection method
does not yet have an automated e2e test, and proxy V2 preview 4 does not use the
?unix-socket=/path exactly as expected.

While pruning fields from the CRD, I found some uncovered code that needed a test.
This adds a test case to make sure that when a customer sets the proxy container resource
requirements in the CRD, the values are actually set on the container.
