The FiniteFirehoseFactory and InputRowParser classes were deprecated in 0.17.0 (#8823) in favor of InputSource & InputFormat. This PR removes the FiniteFirehoseFactory and all its implementations along with classes solely used by them like Fetcher (Used by PrefetchableTextFilesFirehoseFactory). Refactors classes including tests using FiniteFirehoseFactory to use InputSource instead. Removing InputRowParser may not be as trivial as many classes that aren't deprecated depends on it (with no alternatives), like EventReceiverFirehoseFactory. Hence FirehoseFactory, EventReceiverFirehoseFactory, and Firehose are marked deprecated.

Google Cloud Storage Extension
This extension allows you to do 2 things:
- Ingest data from files stored in Google Cloud Storage.
- Write segments to deep storage in GCS.
To use this Apache Druid extension, include druid-google-extensions in the extensions load list.
Required Configuration
To configure connectivity to google cloud, run druid processes with GOOGLE_APPLICATION_CREDENTIALS=/path/to/service_account_keyfile in the environment.
Reading data from Google Cloud Storage
The Google Cloud Storage input source is supported by the Parallel task
to read objects directly from Google Cloud Storage. If you use the Hadoop task,
you can read data from Google Cloud Storage by specifying the paths in your inputSpec.
Deep Storage
Deep storage can be written to Google Cloud Storage either via this extension or the druid-hdfs-storage extension.
Configuration
To configure connectivity to google cloud, run druid processes with GOOGLE_APPLICATION_CREDENTIALS=/path/to/service_account_keyfile in the environment.
