Cédric Jeanneret 475368e9b7 Make healthchecks more strict 
It was discovered that healthchecks aren't really reliable because they
aren't strict enough.

The current patch adds the "standard" options in order to ensure we
actually catch errors soon enough in order to return the actual state of
the checked element.

It also requires a small change for the healthcheck_port() function,
since the "piping" returned a 141 code instead of 0 due SIGPIPE being
sent at some point[1].

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"}]}]}
