Added a garbage collection process to on-disk persistence that removes older documents. This is enabled automatically if persistence is enabled, and the SDK will attempt to periodically clean up older, unused documents once the on-disk cache passes a threshold size (default: 40 MB). This threshold can be configured by changing the setting cacheSizeBytes in the settings passed to Firestore.settings() . It must be set to a minimum of 1 MB. The garbage collection process can be disabled entirely by setting cacheSizeBytes to CACHE_SIZE_UNLIMITED .
Updated gRPC version to support Node 11.
