Parsing-server-ip-from-Heat-output

[Devdatta Kulkarni]

Change the parsing of Heat stack-show command to correctly parse the server-ip.

The heat stack-show command generates a list of two entries for a stack's output. One entry is for the output_key "URL" and other is corresponding to the output_key "public_ip". We want to parse the IP address of the server by parsing the entry corresponding to the "public_ip".

Currently we are picking the first entry from the outputs. See below:

This is incorrect, as the order of entries in the output may not be fixed.

    Correctly parsing the server ip from the created heat stack.

    The heat stack-show command generates a list of two entries for a stack's
    output. One entry is for the output_key "URL" and other is corresponding to
    the output_key "public_ip". We want to parse the IP address of the server
    by parsing the entry corresponding to the "public_ip".
    Currently we are picking the first entry from the outputs.

    This is incorrect, as the order of entries in the output may not be fixed.
