Issue: AAP-54345 / AAP-57129

Implements metrics_utility.library.storage - StorageS3, StorageDirectory, StorageCRC, StorageCRCMutual

storage = StorageS3(
    bucket=os.getenv('METRICS_UTILITY_BUCKET_NAME'),
    endpoint=os.getenv('METRICS_UTILITY_BUCKET_ENDPOINT'),
    region=os.getenv('METRICS_UTILITY_BUCKET_REGION'),
    access_key=os.getenv('METRICS_UTILITY_BUCKET_ACCESS_KEY'),
    secret_key=os.getenv('METRICS_UTILITY_BUCKET_SECRET_KEY'),
)

storage.put('my-remote-filename', filename='/tmp/file_to_upload')

with storage.get('my-remote-filename') as filename:
    open(filename)...

storage = StorageDirectory(base_path=os.getenv('METRICS_UTILITY_SHIP_PATH'))

storage.put('my-relative-filename', filename='/tmp/file_to_upload')

with storage.get('my-relative-filename') as filename:
    open(filename)...

StorageCRC(TODO)
StorageMutual(TODO)

And makes extractors, report savers and packagers use it.
