[ENH] Remove the static HTML QC pages

[DESm1th]

This pull request will get rid of the old static qc pages and instead generates json 'manifest' files that tell the dashboard how to display everything. This will make it easier to drop in new metrics in the future, since they can be generated by any script as long as the outputs land in the qc directory and contain these simple json sidecars.

• Adds a 'Metric' class to provide a uniform interface for QC metric generation code, and sub-classes for each of our existing QC metrics 18a25a0, 77b19fe
• Updates how resources folders are read from datman.scan.Scan 1b6527d, 3f31550
• Moves the find_tech_notes function to datman.utils and updates dm_xnat_extract so it stores tech notes paths in the database d85d5d3, 527f9ce
• Updates dm_qc_report to remove all code that wrote html and instead use the datman.metrics classes to generate metrics 30b9149
