auto-instrumentation

Is your feature request related to a problem? Please describe.

Go auto-instrumentation works differently compared to other languages. Each version of Go auto-instrumentation supports up to a specific Go version. This means that new applications compiled with the latest Go version won’t be automatically instrumented until the corresponding auto-instrumentation tool releases an updated version with support for it.

Describe the solution you'd like

We would like the Operator to auto pull the latest auto-instrumentation image if configured to do so, this will remove the need of manually bumping the version whenever there is a Go (and auto-instrumentation) release.

A configuration option like imagePullPolicy so the image can be pulled "Always".
