Build a file-based catalog

[clobrano]

Why we need this PR

Currently NHC's Makefile creates a db-based catalog, which is deprecated

DEPRECATION NOTICE:
Sqlite-based catalogs and their related subcommands are deprecated. Support for
them will be removed in a future release. Please migrate your catalog workflows
to the new file-based catalog format.
