Disable option in SelectInput

[svrcekmichal]

Is your feature request related to a problem? Please describe.
I've added list of user statuses into our admin page, and transition to few of them should be not possible, the problem is that it's not possible to mark option as disabled. This is supported in material ui, since MenuItem has prop disabled but SelectInput is not passing that prop down

Describe the solution you'd like

<SelectInput source="status" choices={[
  { id: "DISABLED", name: "disabled", disabled: true},
  { id: "ENABLED", name:"enabled"}
]}

Nice enhancement suggestion, and quite easy to add. Would you like to give it a try?

I can try this if it's still available.

It is, please do :)

I created a PR, I hope it's clear.
