Adding the reprocess update type.

[THOR300]

Description

Adds reprocess as an update type. This is desired as we want to perform the parse action in the ingest stage as outlined below. It would seem confusing to then set the Update type as SOURCE_URL to trigger reprocessing so adding as a new type.

update_type_actions = {
    UpdateTypes.SOURCE_URL: parse,
    UpdateTypes.NAME: update_dont_parse,
    UpdateTypes.DESCRIPTION: update_dont_parse,
    UpdateTypes.METADATA: update_dont_parse,
    UpdateTypes.SLUG: update_field_in_all_occurences,
    UpdateTypes.REPARSE: reparse,
}

Also adds the document update config block to hold data like:

DocUpdateConfig(reparse_updates=["cclw.doc.0.1", "cclw.doc.0.2", ...])

Proposed version

Please select the option below that is most relevant from the list below. This
will be used to generate the next tag version name during auto-tagging.

• Skip auto-tagging
• Patch
• Minor version
• Major version

Visit the Semver website to understand the
difference between MAJOR, MINOR, and PATCH versions.

Notes:

• If none of these options are selected, auto-tagging will fail (integrated soon)
• Where multiple options are selected, the most senior option ticked will be
  used -- e.g. Major > Minor > Patch
• If you are selecting the version in the list above using the textbox, make
  sure your selected option is marked [x] with no spaces in between the
  brackets and the x
