### Motivation

*Compatible with flink 1.11 need to use java8 date api in pulsar's primitive schemas.*

### Modifications

*Add Instant, LocalDate, LocalTime, LocalDateTime to pulsar's primitive schemas*

### Verifying this change

Add Instant, LocalDate, LocalTime, LocalDateTime types to the Schema type test

* Added schema information and unittests for primitive schema types

* Fixed unittest

* For primitive types just check for schema type instead of the schema metadata

* Address feedback

* Revert changes to the schemas and only keep unittests
