Plone 6 Cache Updates

[ericof]

Before Plone 6 is released we need to review and improve its caching story, especially considering the heavy usage of plone.restapi.

plone.app.caching

• Review existing profiles and keep only the relevant ones (Maybe drop profile supporting Split Views)
• Move plone.restapi mapping #97 Move RESTApi service class mappings from this package to plone.restapi

plone.cachepurging

• Drop support for Python 2.7

plone.rest

• Implement URL Rewriter to support ++api++ traversal (plone.cachepurging.interfaces.IPurgePathRewriter)

plone.restapi

• Create plone.restapi.caching to control service mappings
• Implement PurgePath that takes into account restapi endpoints (z3c.caching.interfaces.IPurgePaths) PR on restapi
• Create plone.restapi specific rulesets

Documentation

• Provide example of Varnish VCL that supports Purge/Ban and plone.restapi
• Convert README and CHANGES to markdown #114 Rewrite plone.app.caching documentation in Markdown and build it with main docs

I have marked a few tasks here as done. Four out of nine are still open, but maybe some more can be closed already.
