Remove UDP receivers using Jaeger agent code

Details

Jaeger will be removing jaeger-agent code (jaegertracing/jaeger#4739). It is currently being imported by jaegerreceiver. How do contrib maintainers want to handle that?

[atoulme]

Typically we would first deprecate the code, and make sure to have a warning whenever it executes on startup, and in a future release we would then remove it outright.

What exactly is deprecated? Can you please deprecate the jaeger code itself following Golang best practices so we get the deprecation lint errors on upgrade?

[yurishkuro]

In jaeger itself we have a linter that will fail ci if it encounters the use of deprecated functions. So I'm not sure that is the best path. I think can log warnings to users who still use these components in their config, and then some time later remove the components.

What grace period does this repo give to users for deprecated components?
