    [CARBONDATA-Pending] Add dictionary interface for new data load flow

    In this PR, following is added:
    - a BiDictionary interface which can retrieve key by value, or retrieve 
value by key.
    - DictionaryGenerator interface that generates dictionary key from value
    - an implementation (InMemBiDictionary) that uses BiMap from Google Guava 
library as backend data structure. This implementation also supports 
pre-created dictionary.
    Testcase is added for InMemBiDictionary
    I will create the JIRA issue later after it is available
