Non descript error message on failed account creation

[chuysmans]

Describe the bug
When creating an account via the UI, its not apparent that the username must be all lowercase. The bug is the fact that the returned error via the UI doesn't describe this at all:

The adapter operation failed due to a server error

To Reproduce
Steps to reproduce the behavior:

1. Connect to Boundary via the UI
2. Auth Method -> userpass -> Create Account
3. Capitalise the username field and observe the error

Expected behavior
If you run the same command via the CLI the returned error is much more descriptive.

Oct 16 03:15:40 ip-10-0-101-209 boundary[1295]: 2020-10-16T03:15:40.383Z [ERROR] controller: internal error returned: error id=WfbRQxeQdl error="unable to create user: create: password account: invalid login name; must be all-lowercase alphanumeric: invalid parameter"

This same error message should be surfaced in the UI.

We're working on revamping a lot of the errors for the next release, which should help here.
