Use gzip compression

__Proposal:__
As suggest into the [best practices session](https://docs.influxdata.com/influxdb/v2/write-data/best-practices/optimize-writes/?t=Client+libraries#use-gzip-compression), I propose to add the gzip compression on the HTTP client

__Current behavior:__
Now the HTTP request are not using the "Content-Encoding: gzip" and the deflated body in the request

__Desired behavior:__
Add an optional "compression" params and implement the compressed body (I guess only for the POST request)

__Alternatives considered:__
...

__Use case:__
See the best practice [here](https://docs.influxdata.com/influxdb/v2/write-data/best-practices/optimize-writes/?t=Client+libraries#use-gzip-compression)

Start at the Ruby HTTP client entry point and trace the POST request path used for writes. Confirm how an optional compression parameter should control the request body and Content-Encoding header; done means gzip compression is applied when requested and ordinary requests remain unchanged.
