lombok dependency provided scope

[seregamorph]

Fix lombok dependency scope - it should have provided scope (not compile). It reduces the final build size significantly.

moved to parent pom (alternatively could be duplicated in all submodules)

Hi @seregamorph. Thanks for this PR. I'll take a look when I'm back from vacation later in the week.

I need to check this will work all the way back to TeamCity 9.

Also, this SO comment indicates I might need to pass an extra argument to maven.

To clarify further: Lombok is not just a library, it is a processor that modifies the code when compilation takes place. So you need to execute it when compiling, if you switch it to provided scope this will not happen by default (you can force maven to run the lombok processor adding -Dexec.classpathScope="compile"to the command line.)

You can check, no additional parameters required, just execute mvn clean install and it will apply lombok compilation processors. Also most rated comment in this thread gives the same advice: use provided scope: https://stackoverflow.com/a/38454162/3468905
