Add features: Silent Pod and Pod Diagnostics

[marionbarker]

This PR adds the Silent Pod and Pod Diagnostics features to the OmniKit screen for Eros pods:

The Silent Pod and Pod Diagnostics rows are added as shown in the graphic below.

User-facing changes:

• Pod notifications include an option to silence the pod
  • When silenced, alerts are only on the phone, the pod does not beep
  • Pod faults, end of life and out of insulin still alarm on the pod regardless of this setting
• The previous pod row is moved under the pod details row to make it easier to find
• A pod diagnostics row is added to the end of the pod screen
  • various diagnostics rows are added in a new sub-screen
  • Eros pod users can check their pod RSSI to assist in debugging pump communication issues

The before (left) and after (right) screenshots of the Omnipod screen is shown below.

LGTM except for extra spaces in allowDebugFeatures if statements and a big concern about using allowDebugFeatures to conditionally enable displaying the Silence Pod option which I believe should always be available. If this option really must be conditional like this, additional thought and code will be needed to properly handle certain possible cases.

The DIY pump managers will not be used by Tidepool, so I reverted the commit that added the allowDebugFeatures check.

LGTM!

asyncAction and FirstAppear are wrongly pushing view model logic into the view.
