[DE-716] Compression of requests and responses

[apetenchea]

Adding compression of requests and responses, as implemented in arangodb/arangodb#20128

By default compression is turned off, so this change has no effect unless the user specifies one of the newly introduced parameters.

The ArangoClient gets two optional parameters:

• request_compression - Represents the compression strategy, None by default. The reason for passing in an object instead of a string (such as deflate) is to allow the client to fine tune the compression algorithm.
• response_compression - The equivalent of an Accept-Encoding string. This has no effect unless the server is configured to use encoding.

client = ArangoClient(
    hosts="http://127.0.0.1:8529",
    request_compression=DeflateRequestCompression(),
    response_compression="deflate",
)

A new documentation page has been added specifically for guiding users on how to use compression.

Small optimization, eliminates whitespace from the JSON structure.
