fix(cloudrun): delete protection, default service names

[glasnt]

Two updates to Cloud Run samples

fix(cloudrun): make delete protection explicit

fixes #730

Adds deletion_protection = false to tested Cloud Run services (which fixes testing, while not adding things that aren't required for untested samples)

fix(cloudrun): update cloud run services names to unique values

fixes #164

Since most Cloud Run service samples are being updated anyway, use named services when useful, otherwise use "my-service" (don't encode product name into product instance name)
