Ckan: Deprecations in CKAN 2.7

[TkTech]

This ticket is for tracking the upcoming 2.7 release aimed at deprecating or flagging behavior changing in the next major release. I would also recommend we make this an "LTS" kind of release we'll backport fixes to for quite awhile.

Deprecated

API

• [x] /api/rest/* will be removed in favour of action API introduced in CKAN 2.0
• [ ] All *_html actions will be removed in favour of simple Jinja2 templates.
• [ ] All *_activity_list actions will be removed in favour of a single activity endpoint.
• [ ] All actions where it makes sense will be paginated. Currently many methods return complete sets [built in memory] which cause significant performance problems.
• [ ] Activity-related actions will switch to sorting and offset based on timestamp.

Frontend

• [x] Announce deprecation of Bootstrap 2 on the next release (2.8) See https://github.com/ckan/ckan/pull/3547#issuecomment-302437127

Misc.

• [ ] The legacy revisions controller (/revisions/list, etc...) will be completely removed.
• [ ] The package history view will be completely removed. Instead, you can view the package at any point in time based on Activity records.
• [ ] Revisions/VDM themselves will be deprecated in favour of improved activity.
• [ ] Celery based tasks in favour of RQ jobs
• [x] Feeds must use use v3 api endpoints (#3542)

Fixes

• [ ] number_of_packages and number_of_revisions changed from dynamic fields to pre-calculated trigger-based fields on Users, significantly improving performance for both logged in users and user_list. (Requires migration)
• [ ] Activity APIs and views now respect permission_labels, fixing many issues. (Requires migration)

I put /api/rest at the top because it seemed important :-)

From my point of view, the Celery-based background jobs can be deprecated in favor of the RQ-based solution. Code, documentation and deprecation notices are in master.

Is beta.ckan.org running the latest built?

when this goes in I'd like to switch all use of unicode in validators to unicode_only https://github.com/ckan/ckan/pull/3428/files#diff-38644dde5577e621a00643c43bfec0feR120
