Remove dead API code
Update MCPGraphing for SetUnitVariable & exit codes

refs #6386

Display variable and variableValue or microservicechainlink (whichever
is set) for task type SetUnitVariable, as well as non-0 exit codes from
MicroServiceChainLinks. Nodes that start chains are bordered in dark
gold.
Update createStructuredDirectory

Move createStructuredDirectory into archivematicaFunctions and rename
create_structured_directory so it can take advantage of the directory
constants and functions already there.  Add manual normalization
constants to that file as well.  Update all callers, remove now
deprecated archivematicaCreateStructuredDirectory.py/sh, and do some
minor cleanup.
Add AIP reingest button

refs #6488

Add Reingest button to the archival storage tab which POSTs to the
storage service reingest endpoint.  Add reingest form and storage
service helper to support this
Initial updates for Re-ingest AIP

refs #6488

Reuse existing DIP from AIP MSCLs and update for newer, more general use
case.

Update determineAIPVersionKeyExitCode to default to the only path
available, as there are no exceptions to AIP processing currently.
Remove assignFauxFileUUIDs and renameDIPFauxToOrigUUIDs as we won't be
using fake IDs to separate the original SIP from the reingested AIP.

Many SQL updates:
* Fix typos, remove bizarre links
* Update microservice groups to make them more contiguous
* Verify checksums moved to after metadata processing, as metadata
generates checksums too
* Metadata reminder moved to before submission documentation and
metadata processed
* Remove old style file ID
* Update reingest chain to use existing DIP and AIP creation, instead
of custom path
* Add processingMCP to reingest path
* Remove useless magic link, clean up setup for normalization and
setting which normalization node to go to
* Delete all TasksConfigs and StandardTasksConfigs that have no foreign
keys pointing at them
Rename DIPfromAIP to reingest AIP

refs #6488

Rename MicroServiceChainLinks and watched directory to reflect actual
purpose.
MCPServer sets currentPath in watchedDirectories

When starting a chain from a watched directory, ensure the unit's
current path matches the one found in the directory.  This can happen
during AIP reingest, where the last know location is not the watched
directory it is currently in.  Also, some cleanup.
Entry filter in browse is configurable

The filter to determine which files/folders are displayed when browsing the
storage service (ie starting a transfer) is now a parameter, instead of
builtin.  Default is still to display folders but not files.
Stub of add metadata files
