feat(node): Compression support for http transport

[lobsterkatie]

Note: This is an exact duplicate of #5139 and #5203, both originally by @timfish, which accidentally got merged into the 7.x branch rather than master.

#5139:

This is mostly stolen straight from the Electron transport.

This will help with attachments!

#5203:

#5139 introduced a subtle bug where options.headers was modified which causes headers to leak between requests. This means requests after a compressed request will be incorrectly marked with content-encoding: gzip.
