Check compatibility with older APM Server versions

See original GitHub issue

Whenever we leverage new features in the Intake API, we have to make sure we are still compatible with older APM Server versions, possibly by conditionally making use of these features, based on the APM Server version(s) we are connected to. We currently do this for allowing non-string values for context.tags.

allowing int for context.request.url.port https://github.com/elastic/apm-server/commit/af76d15f4ab07468d4b5ae70ed11d34b52014c1a#diff-b3c35663f19380d55a7b0b375e1aeb4a

I feel this is something that would be a good extension of #882 (check agent payloads against server protocol definition), in the way that instead of checking the “current” version, we would also check for known versions we are supposed to be compatible with.

However, checking json schema might not cover everything regarding compatibility.
