As a user, I need to be able to pick a username that isn't already taken

[mikepif]

Description or User Story

The account creation page requires a username, so to enable account creation we need to be able to check if a username provided by the user is not already taken.

Frontend Tasks (to be completed by Dev)

• Username input field with validation state based on availability of username

Backend Tasks (to be completed by Dev)

• GraphQL end point for querying user by username, and should not return any user info other than the username or true/false if the username is taken. Also should not require authentication.

Acceptance Criteria

• Validation state reflects database values
• Route does not return any user info
• Route returns true for a pre-existing username
• Username is case insensitive

@mikepif PR #102 is ready with username lookup.

@Samara-Strauss Why is this ticket in the icebox? I think we're doing active dev on this. Back-end has support for username lookup.

[Samara-Strauss]

I'm not sure. I haven't seen this ticket before.

I've moved this to In Progress.

[ronaldheft-gov]

@mikepif Are you handling updating this ticket? This should be done from the back-end perspective now.

[Samara-Strauss]

Wondering if this is done from a FE perspective as part of #24. @mikepif let us know if there is still work to be done here or if we can close this out.

[leahbannon2]

@mikepif to verify that this is done

[Samara-Strauss]

Initial work was done, but there was a bug found that needs to be resolved before we can close this out.
