Support Scan Planning in Iceberg Rest Client

[singhpk234]

About

Presently there is no IRC client implementation supporting Scan Planning. This is kind of a pre-req for the IRC server to support Scan planning.

There was effort in past to get the scan planning in, apparently it didn't went through the end. Checked with the author if they plan to pick it up, seems like they don't have cycles for the same and they were fine by me pushing this to the end line.

This issue aims to track the progress of this effort.
