Make the clearFilterControl optional when using data-show-search-clear-button

[merinosky]

Description

Currently when adding the search clear button through data-show-search-clear-button option the filter controls, if added, are also cleared. My table manages filters and search independently, so I would like to be able to clear the search input (using data-show-search-clear-button) without affecting the filter controls (in my case there is only one filter control outside the table).

Could be this feature configurable via a table option so we can decide whether clearing search affects filter controls or not?
