Description: Added support for h2c traffic on http servers generated by confighttp.

This is in preparation for combining gRPC / HTTP ports for OTLP (see #3765 for the complete use case)

Testing: The HTTP receive tests have been updated to check for both http/1.1 and h2c traffic when "insecure" mode / non-TLS is used.

@bogdandrutu @tigrannajaryan @jpkrohling Attempting to break down the gRPC/HTTP port combination work. This PR is a prerequisite to #3765 😄

The code looks sane, but I would love to see a benchmark in the test suite to have an idea of what this change causes in terms of performance.

Good idea regarding the benchmark! 💡

Before:

goos: darwin
goarch: amd64
pkg: go.opentelemetry.io/collector/config/confighttp
cpu: Intel(R) Core(TM) i7-9750H CPU @ 2.60GHz
BenchmarkHttpRequest-12    	  312465	      7150 ns/op	    4105 B/op	      45 allocs/op

After:

goos: darwin
goarch: amd64
pkg: go.opentelemetry.io/collector/config/confighttp
cpu: Intel(R) Core(TM) i7-9750H CPU @ 2.60GHz
BenchmarkHttpRequest-12    	  311053	      7010 ns/op	    4121 B/op	      46 allocs/op

I also added a benchmark to verify that any performance delta would only be when using noTLS settings.

TLS traffic before and after should have no deltas.

Consider to have this as a separate test only for this config. It is not recommended to add this and be run only for one of the "sub-tests".

@bogdandrutu Looks like this PR was pretty close. I was not closely involved in this work, but I can get it reopened if it looks good to you.
