pass values on stdin to zabbix_sender rather than temp file
add zabbix failure and logging functions

zbx_fail() will print ZBX_NOTSUPPORTED on stdout so that passive agent items will become 'unsupported' on server side

setLogLevel() returns a logger object to aid with debugging
catch popen failure raise more info

report full command line in exception if zabbix_sender fails to run or returns error
raise url connection failures
add --config option for future use by sendValues()
init logging at debug, add agent config to sendValues()

provide default full path to zabbix_sender
include agentconfig in sendValues() call
rename sendValues() zabbix_sender() pass exceptions to zbx_fail()

validate URL opts in get_opts() not main()
unself agentconfig default option to not break old method

old method was short circuited by presence of default
mv bin/fetch.py bin/check_apache
define apache.status item UserParameter to trigger trapper items
replace old template with new style

This template removes the hostname from the item keys,
it is renamed Template_App_Apache_Status, and it includes a couple of graphs.
move old template to conf/ dir
Revise for new name and mode of use
fix agentconfig arg typo
