  - Make healthcheck script output unbuffered

    A subprocess.Popen object is created instead of
    convenience check_output() routine usage to allow
    unbuffered reading stdout from asynchronously
    running subprocess.

  - Support running healthcheck in any mode supported

    So far it was only possible to run health checking
    script with a default option of 'health'. This patch
    allows passing through to healtcheck script any mode
    that it supports via --health-mode runtime option.

  - Always show healthcheck output if it was run

    This patch changes the default behavior of showing
    healthcheck script results. So far output was printed
    only in increased verbosity mode but the proper action
    should be to print it whenever it was called.

    A bug in exec_healthcheck() routine is also fixed
    (subprocess.check_output() returns byte string, not
    an object with 'output' attribute).

  - Support SSL certificate based authentication to kube API

    With this change script by default connects to kube API
    performing SSL authentication with certificates that it
    tries to read from kube config. A flag of '--no-ssl-auth'
    is provided to disable this behaviour.

  - Add Kubernetes class to track API connection settings

    This patch moves get_resources() routine into Kubernetes
    class. It's object now holds all needed API connection
    properties and tracks it's state to avoid passing these
    settings through intermediary functions all the way down
    to actual API calling routine.

    Additional checks are added in get_resources() to produce
    more meaningfull debug info in case of connection failure.
