Refactor Segment Name Generator

[KKcorps]

Currently there are three issues with SegmentNameGenerator classes -

• The implementations need to be supplied with exact arguments instead of general segment name generator config. e.g. You need to provide dateTimeFormatSpec, pushType , excludeSequenceId etc. but instead you can simply pass segmentNameGeneratorConfig to the constructor and let the implementation take care of extracting out props.

• Any change to segmentName logic requires changing the implementation classes. We can rely on something like templates to generate the segment name rather than having to implement code change.

• A lot of segment name generator props are duplicates in BatchConfigProperties as well. Addressing 1 should also help addresses this.
