Website: Update customer migration webhook (#12269)

Closes: https://github.com/fleetdm/confidential/issues/2964

Changes:

- Updated the `receive-from-customer-fleet-instance` webhook to send a
request to a Workspace One OAuth URL to get the authorization token used
to send requests to a Workspace one instance.


Before this is merged, we will need to:
- [ ] remove the `sails.custom.config.customerWorkspaceOneTenantId` and
`customerWorkspaceOneAuthorizationToken` config variables.
- [ ] Add two new config variables:
`sails.config.custom.customerWorkspaceOneOauthSecret` and
`sails.config.custom.customerWorkspaceOneOauthId`

.
