Allow support for "contains" condition for checkbox control type

[tristantyler]

Contains is disabled for checkboxes here .

DataStage Canvas is adding functionality that allows a user to change a properties control type. For example, a checkbox can become a textfield if a user wants to parameterize that property.

Parameterize refers to replacing a properties value with something like "#MyParameter#". This MyParameter can refer to any value. Certain conditions that use "contains" are needed to process logic related to this, but since "contains" isn't allowed for checkboxes we cannot do this processing.

Example of a similar usecase but with oneofselect as the original control type instead

Hi @tristantyler, we don't support contains for checkbox controls because checkboxes are of type boolean while contains validates against strings or arrays. This looks like a very specific use case for your application. Can you take a look at using custom conditions? https://github.com/elyra-ai/canvas/wiki/3.5-Common-Properties-Custom-Components#custom-condition-operators

@caritaou Thanks for the quick response. I'll look into that. Thank you!
