snmpm:sync_get/4 is schedulled for removal in OTP 25.

I am not sure if those changes are sufficient, gen_statem requires for example callback_mode() hook that i think is missing, and i think it also adds extra argument to state callback functions it calls, so i am not sure if this will be working as expected.

Thanks for the feedback, @prefiks; I reduced the scope of the PR to snmpm:sync_get/4. I'll work on gen_statem in another PR: there is indeed a conversion guide from gen_fsm.
