Make email type in SCIM message configurable

Some serviceproviders are picky on where the value for the email address is send. e.g. AWS requires the type to be other, while GCP requires it to be work

• Add a selector to openconext-Manage provisionings, home, work and other
• Use other if not configured (default)
• Change the SCIM messages to send the email address as the configured type
• If multiple types are configured, send the email multiple times

examples:

{
  "emails": [
    {
      "value": "alice@example.com",
      "type": "work",
    }
  ]
}

{
  "emails": [
    {
      "value": "alice@example.com",
      "type": "other",
    }
  ]
}

{
  "emails": [
    {
      "value": "alice@example.com",
      "type": "other",
    },
    {
      "value": "alice@example.com",
      "type": "work",
    }
  ]
}

Start by locating the openconext-Manage provisioning configuration and the SCIM message generation described in the issue. Trace how the email value is currently emitted, then verify that the default is other, configured types produce corresponding entries, and multiple types produce multiple entries.
