Allow to remove TableNamePrefix on operation level

[Dreamescaper]

Fixes #3470

Description

Allow to remove TableNamePrefix in operation-level configs by setting an empty string.

Motivation and Context

In some cases I have most of the tables with suffix, and one or two, which do not correspond to such convention. In this case I would like to be able to use TableNamePrefix globally, but remove it per operation.

Testing

Added unit tests.

@Dreamescaper Shouldn't the PR title and the commit message read "...remove TableNamePrefix" instead of TableNameSuffix?
Unless I am missing something.
