binding config schema validation for unused properties

[ankitk-me]

Fixes #808

[jfallows]

Given that server options are a superset of client options, is there not a way to specify the common subset once, and then conditionally include the additional options properties for server?

Note:

Prior to this change, options & properties declared under options can be configured irrespective of the value configured for kind.
Below mentioned changes are done to restrict the configuration of unused properties.

I don't see any reference to entry0 is this expected?

[ankitk-me]

this script is added to test negative scenario(if kind: server, entry property is not allowed). expected output is JsonException. So I thought having an entry defined might not be required.
