Fix cluster reconciliation logic

When reconciling clusters, airshipctl points the bootstrapInfo and
managementConfiguration to an entry named default, and the user is
unaware of this change. The result is that user settings are ignored
unless the user defines settings under entries named "default". This
change updates the cluster reconciliation logic to do this only when a
cluster is added to the airshipconfig by airshipctl.

Fixes #244
