Create a Connections context menu group next to Modeling group

For source models, the Modeling action now contains a number of connection or translator related actions that really don't have anything to do with modeling.

• Create a Connection menu group and place below Modeling group
• Move the following actions to the Connection group
  • Create Data Source
  • Edit Translator Overrides
  • Remove Connection Info
  • Set Connection Profile
  • Set Translator Name
  • View Connection Profile Info
• Maybe group these into Translator/Profile actions with separators
