feat(Codaveri Live Feedback): Allow [Get Help] on all programming questions

[cysjonathan]

Current status

[Get Help] button only exists for Codaveri-enabled programming questions (e.g. Programming questions which use Python language and Codaveri evaluator)

Expectation

[Get Help] button will be available for all programming questions.

Requirements

1. Once Codaveri supports feedback on all programming questions, we should allow Get Help button to be configurable on all programming questions.
2. Allow question level control to enable/disable [Get Help]
