security/all: fuzz input formats with any parsing

[odeke-em]

In this repository, we've got a bunch of parsers and converters between various formats. The parsing problems and crashes have been reported by users or by us during integration testing. However, evidently we are human and can't exhaust combinations or inputs that can be sent by malicious actors. In order for us to deploy this software to production, it would be great for us to pass in automated inputs and fuzz the living heavens out of the service and fix issues as we encounter them.

There is https://github.com/dvyukov/go-fuzz that we can use, as well as others.

Perhaps let's keep this issue open for cycles of testing and fixing.

I started working on this but encountered an issue with go-fuzz and go modules dvyukov/go-fuzz#195 (comment) so that's stalled for now.

@tigrannajaryan @pjanotti do we plan to do this in OpenTelemetry Service?
