Warmup (JMH Core 1.35 API)

```
@Target({METHOD,TYPE})
@Retention(RUNTIME)
@Inherited
public @interface Warmup
```
Warmup annotation allows to set the default warmup parameters for the benchmark.

This annotation may be put at Benchmark method to have effect on that method only, or at the enclosing class instance to have the effect over all Benchmark methods in the class. This annotation may be overridden with the runtime options.
