Enhanced HTTP delete API to allow for more flexible input and response

[mdorf]

Our current implementation of http.delete method only accepts a single path to delete and returns the raw HTTP response object:

delete /path/to/resource/:resource_id

The enhanced version is fully backwards compatible with the old format, but also adds the ability to call delete REST endpoints that accept multiple resources:

delete /path/to/resource?resource_ids=['resource1, 'resource2', 'resource3']

It also allows for an optional JSON response to be returned from the API to facilitate better error reporting.

Usage:

res = LinkedData::Client::HTTP.delete("/path/to/resource", { resource_ids: "[3,5,7]" }, parse: true)
my_var_from_resonse = res&.my_var
