Error message returned is not meaningful, when tried reimage a with a package instead of Base_OS

[Bharat Kumar]

Tried to reimage with a package ID instead of base_OS from server-manager, but the error message returned was conveying why reimage was failed.

Tested on R2.20 Build #2

Logs:
====
root@nodec32:~/sm_files# server-manager reimage -F --where ip_address=10.204.221.3 ubuntu-12-04
{
    "return_code": 9,
    "return_data": null,
    "return_msg": "Error in re-imaging server"
}
