Add compression to LineProtocolClient

[stmax82]

I added gzip compression to HTTP POST requests.

Quick tests have shown that it reduces Content-Length down to 50% (for short single point requests) and down to <10% (for large multi-point requests).

Compression can be enabled using an optional parameter of the LineProtocolClient constructor. Default is off so the behavior should be the same as before.

Hi @bednar,

Could you please update CHANGELOG.md and add unit tests to cover your changes?

done - I updated the changelog and added a few tests for the LineProtocolClient with and without compression.
