[exporter/datadog] add compression

[fabio-viana]

Data sent from OpenTelemetry collector is not compressed and enabling gzip compression would improve bandwidth usage.

Similar to what was done in this PR: #1747

@mx-psi Do you have any estimate for this feature?

[mx-psi]

@lchayoun apologies for the delay, I was on vacation :)

For most of the payloads we send, adding compression depends on us updating the internal library used for interacting with the backend. Both the internal library update and adding compression are in our roadmap, and I have written down that we have customers interested on this so that we can prioritize accordingly.

Hi @take-five, the internal library update has not been done yet, I can provide an update when the work is started
