    Specification of various Window and Trigger APIs in Samza

    - Defined APIs for specifying different types of windows - sessions, tumbling, global
and keyed variants.
    - Defined APIs for specifying early and late triggers for a window.
    - Standardized all above Window types to be expressed as a combination of default, early
and late triggers.
    - Defined classes for different types of trigger specifications.
    - Hide the WindowState class from programmers and move it from samza-api to samza-operator.
We can choose to add it later if need be.
    - Removed some implementation classes in Window and Trigger. We can revisit them later
when we implement Windows.
    - New API for specifying Time durations meaningfully in Samza.
    - Unit tests for most of the above changes.
    - Misc. Documentation, readability related changes to public APIs.
