Complete webhook updates

[snacktavish]

Studies github webhook route is working - but isn't checking that the docstore matches

https://github.com/OpenTreeOfLife/otindex/blob/webhook/otindex/views.py#L277

Also, route for taxon amendments doesn't exist yet.
(although I started a stub)

Cache clearing code now exists! should be called by otindex. {API base URL}/clear_cache_keys/{key OR regular expression}

Example: https://devapi.opentreeoflife.org/clear_cache_keys/^clearme.*
[needs URL-encoding beforehand]

@jimallman What would clearing the study list for the curator look like? (https://api.opentreeoflife.org/cached/v3/studies/find_studies verbose=true)

[jimallman]

Try the new API method, i.e. https://devapi.opentreeoflife.org/clear_cache_keys/.*find_studies.*

[snacktavish]

Right after that, call https://devapi.opentreeoflife.org/cached/find_studies, to refresh the cache.

[jimallman]

That refresh call probably needs some additional query-string args; see the footer details on devtree curator...

[jimallman]

@snacktavish OK, here's a (simplified) cURL call that's equivalent to what the web-app actually requests.

curl 'https://devapi.opentreeoflife.org/cached/v3/studies/find_studies' \
  -X 'POST' \
  -H 'Content-Type: application/x-www-form-urlencoded; charset=UTF-8' \
  -H 'Accept: application/json, text/javascript, */*; q=0.01' \
  -H 'Cache-Control: no-cache' \
  --data 'verbose=true'

The more closely you can match this call, the more likely you'll populate the cache with a complete and correct cache key.
