Implement `benchmarking` functionality (Library).

[sokimaaa]

Context

• We need the library for general purpose things
• For now in scope of this library, we need to have Benchmarking logic to evaluate our code performance e.g. how many seconds does method take?

Acceptance Criteria

• Created annotation for benchmarking
• Annotation should be allowed for method level
• Annotation should be well documented
• Annotation should evaluate time of method invoking in ms and simply print in log.
• There should be two types of messages, e.g. DEBUG/TRACE and WARN if critical amount of execution time is taken
• Should be leverage to turn off annotation logic by application.properties, e.g. when true is set.

Technical Details

• Explore what is Spring Bean Lifecycle
• Explore what is Bean Post Processor
• Explore what is Spring Proxy Bean
• JFYI the same logic could be implemented using Spring AOP, but I dont want to use it for time being
