Add the option for POST for select endpoints in the common APIs page

[acbuyan]

Endpoints:

/biocache/occurrences/offline/download /biocache/occurrences/facets/download /biocache/occurrences/search

[sughics]

• POST /occurrences/offline/download- already supported by biocache-service, an additional resource path for the POST option can be added to the common api list
  • POST /biocache/occurrences/facets/download - POST not supported by biocache-service - implementation needs to be added to biocache-service app first and then added to all published API spec lists
  • POST/biocache/occurrences/search - POST not supported by biocache-service - implementation needs to be added to biocache-service app first and then added to all published API spec lists
