WCS-T performance improvement — at Initial Version

Description
The WCS-T ingestion workflow (from wcst_import, via WCS-T petascope to rasdaman) needs to be instrumented and optimized where possible.
Some initial ideas
- Parallelize WCS-T in petascope
- Adding an ORM for the relational database would make this simple
- Parallelize wcst_import
- Refactoring the metadata access patterns, there are many redundant queries
- Pooling the rasdaman requests, we can create a queue of them so that we do not wait on each response before processing the next.
- Reading file information with GDAL could be a bottleneck
I'll try to make initial profiling so we have a better idea of how time is spent.
