Handle data connection updates without forcing recreation of content

In the online version of power bi, if you change the account the SSAS connector runs under, the connection in powerbi becomes cached and cannot be updated. Additionally, changing servers from for example one Azure server to another breaks the connection.

For Enterprise customers to use power bi, it is necessary for us to be able to point existing data connections to new configuration locations.

Without this capability, if we move SSAS servers or change the account that the connector runs under, we have to manually create a new connection for all of our users and they must re-create their content that used the old connection!
