GCSBucket

When user wants to use GCSBucket service from GCP for persistence, he can use GCSBucket persistence feature from restonomer.

The GCSBucket persistence needs below arguments from the user:

Input Arguments	Mandatory	Default Value	Description
service-account-cred-file	Yes	-	The filepath of the GCP service account credentials
bucket-name	Yes	-	The name of the Gcs bucket where the dataframe files need to be stored
file-format	Yes	-	The format (json/csv/parquet) of the files to be persisted for the response dataframe
file-path	Yes	-	The path of the directory where output files will be persisted
save-mode	No	ErrorIfExists	This is used to specify the expected behavior of saving a DataFrame to a data source. Expected values are (append, overwrite, errorifexists, ignore)

User can configure the S3Bucket persistence in the below manner:

persistence = {
  type = "GCSBucket"
  service-account-cred-file = "/user/secret/creds/gcs-cred.json"
  bucket-name = "test-bucket"
  file-format = "JSON"
  file-path = "test-output-dir"
}

Now, in order to make this work, user needs to provide a correct service account credentials file.
