Unable to handle and recover from invalid user configuration

[ufukty]

Context

• Refactors the config pipeline and fixes improper access to language-specific configuration #50 revealed omits incorrect user configs and Prompt user for semantic issues on user configuration #52 filed a suggestion to correct.
• During the refactor of improving the organization between config reader, compiler, cache store, editor decorator and the extension lifecycle controller, I realized it is not obvious how the initialization of an editor decorator should proceed when there is a such incorrect user config problem.
• The ambiguity is sourced from the uncertainty of whether the incorrect config prompts should be handled at a centralized place (over the individual editor decorators) in order to avoid prompting the user repeatedly.
• In case of the prompting handled at a centralized place (above the decorators, eg. the lifecycle controller) then the partial initialization of decorators should be settled.

Problem

Refactor is blocked.

Suggestion

• Settle the decision on how the config errors handled and implement changes accordingly.
