Zero Silent Failures: Notification to user that system is not working when CC Providers selected and services do not load

[eselkin]

User Story or Problem Statement

Currently, as a user, if I select "Community providers (in VA's network)" and the /facilities_api/v2/ccp/services request does not succeed, I am not notified but I cannot enter anything to proceed (because the combobox doesn't work).

Description or Additional Context

The combobox loads options to suggest options when you type something, but if the suggestions do not load (with the codes for use in the subsequent requests), then the system will not be able to search.
