doc/readme: announce the deprecation
conftest: reuse tshistory testutil helpers
remove supervision and formula support

This has moved to tshistory_supervision and tshistory_formula
(by subclassing, with their own tests).
api/unwraperror: make sure we raise something in case of a 400 (bad query, input validation)
Added tag 0.8.0 for changeset 18d7c0c8e9d3
api/group_formula: also honor the type errors

This is caught in the tshistory test suite.
api/delete: do not complain if the remote object (series or group) to be deleted is not there
api/groups: add bound formula support
api/groups: add formula support
api: complete the stored group support
api: basic stored group support
api: raise on 404 (will avoid unneeded confusion)
adjust to changes in tshistory/tshistory_rest
api/strip: implement the http client side
pkg: we are now only py3
Added tag 0.7.3 for changeset 1a69182a9b04
dates: do not crash when presented with a stdlib datetime object
highlight the fact that we do not handle plain datetime objects

Which is un-nice.
