Cluster create hides error

[Madhuri Kumari]

When some exception is raised while creating cluster for example ClusterNotSupported, no information is reported anywhere. Also no cluster entry is made in db which hides the error. We need to look into logs to find out the reason.
IMO, we should create a cluster entry in db with status 'CREATE_FAILED' and status_reason set to the error message.

    Add exceptions to cluster db to show failures

    After changing create to async operation, all the exceptions goes hidden
    and no db entry is created to show the actual failure. One has to go through
    the logs to find the actual error. This patch creates a db entry in cluster
    table to show the actual error in column 'status_reason'.
