Add LocalDate/LocalDateTime/OffsetDateTime/ZonedDateTime/Instant support for query and filter

[SinaiNIN]

For now, the current library version does not support query and filter when we tried to query with where condition on LocalDate/LocalDateTime/OffsetDate/ZonedDateTime/Instant.

The error while query is

{
      "message": "Exception while fetching data : Unsupported field type class java.time.LocalDateTime",
}

The error on console log:

java.lang.NoSuchMethodException: java.time.LocalDateTime.(java.lang.Object)
at java.base/java.lang.Class.getConstructor0(Class.java:3350)
at java.base/java.lang.Class.getConstructor(Class.java:2152)

closes #157

@SinaiNIN Great PR! Thank you for contributing. Seems like Travis is failing on the new test you have added because of missing Authors data in data.sql.

We also need more test coverage for new date/time datatypes added to predicate builder. It is best to cover them in a separate module similar to https://github.com/introproventures/graphql-jpa-query/blob/master/graphql-jpa-query-schema/src/test/java/com/introproventures/graphql/jpa/query/converter/GraphQLJpaConverterTests.java

Let me know if you have any questions or comments.

@SinaiNIN If you add new test record to Books and Authors, it will break a lot of existing unit tests. It would be best to amend existing records with dateOfBirth and releaseDate and add new tests to cover LocalDate time support...

@SinaiNIN Can you, please, remove \n and \t from queries?

[SinaiNIN]

@igdianov Noted, Thanks

[igdianov]

@SinaiNIN Can you extract your tests into a separate a package with its own test class, data.sql and test model?

[SinaiNIN]

Yes, I can. It would be better.
