Move data bucket creation out of the data_ingestion TF (#1530)

Summary:
Pull Request resolved: #1530

The data bucket creation was previously bundled into the data_ingestion
terraform template. This prevents limiting the s3 access to only the
necessary bucket for the PCE, which will be updated in a followup.
