Nozomi Kawamoto f15417d662 Support IPv6 for HTTP request 
This http-healthcheck always fails in the case the request is against to
IPv6 address.

Usually, the socket in IPv6 return a tuple that contains four values but
only two values in IPv4.

Currently, only two variables are defined to store return values.
Therefore when extract the return value of socket.getpeername() in IPv6,
an ValueError exception is raised and then healthcheck fails.

This change restrict the return value of the socket.getpeername() to
return only first two elements regardless of IPv4/IPv6.

Health check commands

The scripts in this directory are meant to implement the container-healthcheck blueprint. They are written to be compatible with the Docker HEALTHCHECK api.

The scripts expect to source /usr/share/tripleo-common/healthcheck/common.sh. If you want to run scripts without installing to that file, you can set the HEALTHCHECKS_DIR environment variable, e.g:

    $ export HEALTHCHECKS_DIR=$PWD
    $ ./heat-api
    {"versions": [{"status": "CURRENT", "id": "v1.0", "links": [{"href": "http://192.168.24.1:8004/v1/", "rel": "self"}]}]}
    300 192.168.24.1:8004 0.002 seconds

Notes about changing healthchecks

Because healthchecks are provided via a package when building containers, you cannot rename or remove a health check in combination with a change to a, file in tripleo-common/container-images/. Changes need to be backwards and forwards compatible when updating healthchecks. You may also need to land a new healthcheck first and update the container build process in a subsequent change that lands later.
