'changed' key is not defined when task fails

Typo: assign not equal in boolean guard variable

Fix TypeError when using old simplejson lib.

On some very old simplejson does not support the 'encoding' and give
following exception:

   TypeError: __init__() got an unexpected keyword argument 'encoding'

This fix runs json.dump with no encoding key (such as before #a023cb) on
TypeError exception only.

Typo when variable controlling list of hosts left as available

Remove print statements

This was apparently an oversite, as it has never been configurable
despite having a module parameter for the timeout.

* Added capability to support multiple keys, so clients from different
  machines can connect to a single daemon instance
* Any activity on the daemon will cause the timeout to extend, so that the
  daemon must be idle for the full number of minutes before it will auto-
  shutdown
* Various other small fixes to remove some redundancy

Fixes #5171
