Define a generalized function for display_submission_*

[hkmatsumoto]

Changes:

• Define a generalized function for display_submission_*, since those functions will be very similar to each other.

@takitsuse I think what @vkartik97 meant was using a single submission_result util function to extract all useful content. Adding a new argument in the function i.e. display_submission_result(submission_id, file_name) where file_name can be stdout, stderr etc. Currently, we have all the implementation in utils and using it as a wrapper in the root directory for click library.

Okay, is @pushkalkatara's comment what you ment @vkartik97?

Defined a generalized function as @pushkalkatara's proposal.
@vkartik97 Could you take another look?
