[improve][pulsar-functions] Make Pulsar Admin Client accessible in source and sink functions

[mehrdad-hassanabadi]

Motivation

Currently Pulsar functions using Context have access to PulsarAdmin client instance. By moving the getPulsarAdmin method from Context to the parent interface BaseContext we can provide the same access to source and sink functions as well. This would provide sources and sinks access to topic stats in order for them to make decisions with regards to scale and load handling, throttling, etc.

Modifications

The getPulsarAdmin method from Context to the parent interface BaseContext.
