[ffalor]

This PR addresses the following issues:

  • Adds support to retrieve the uninstall/maintenance token from the API.
  • This should make it easier when uninstalling multiple systems w/o using a bulk maintenance token.

• 104

  • Adds the ability to hide (send to trash) the host from the Falcon console UI.
  • This provides the ability to prevent duplicate hosts on the Falcon console, as well as an easy way to keep the console clean.
• Added API authentication support
• Added error code handling to provide better messaging
• Added the ability to get the AID
