Label deprecated in Code based for measures but we still use in the UI

[royendo]

Describe the bug
Are we using Label or Display Name moving forward, UI and YAML are incosistent

rill/runtime/compilers/rillv1/parse_metrics_view.go

Line 47 in 68383e1

Label string // Deprecated: use display_name

Expected behavior
Change the UI to Display Name for less confusion

The actual display columns needs changing but we should also:

• Map to display_name key in yaml files
• For metric views that was created pre-deprecation we should "migrate" a measure or dimension to use display_name instead of title/label when edited.

To confirm, is the UI supposed to read "Display name" not "Label"? @jkhwu

[mindspank]

Yes, as per design mocks its Display name.
We have also deprecated the actual yaml property label and title in favour of display_name
