[fix][io] KCA: 'desanitize' topic name for the pulsar's ctx calls

[dlg99]

Motivation

Some kafka connectors use topic name to e.g. create table names but pulsar's topic URI does not comply with requirements of the table names. This problems either handled by the connector or by KCA if sanitizeTopicName is set to true.
Some kafka connectors use pause/resume API, in that case sanitized name has to be converted back to original URI to pass to Pulsar's components.

Modifications

Provided a way to resolve original topic URI.

Added unit test.
