New extract command

New command is available to perform extraction with the Event Tag database from the command line:

source /afs/cern.ch/sw/lcg/external/Java/bin/setup.sh
extract
	-manager [CERN|CHICAGO], default = CERN
	-python <Python options file>
	-url <worker ip:port>, default = http://lxvm0341.cern.ch:10001
	-key <insider key>
	-output <output Root file>, default = test_<random>.root
	-query <sql query>
	-collname <collection name>
	-lumi <luminosity>, default = Unknown
	-release <release>, default = Atlas,takeFromEnv
	-conn <connection string>
	-target <target directory>, default = /tmp
	-atts <requested attributes>, default = RunNumber,EventNumber
	-email <notification email>
	-lumiencode <is luminosity encoded ?>, default = False

The user can choose the (Athenaeum) extraction manager (-manager) and the extraction worker (-url). All options can be collected in a Python options file (-python). Other formats of options file will soon follow. The options are taken as they appear on the command line and the options files. That means that an option file will overwrite all command line options set before, but its options will be overwritten by command line options set after.

When performing tag extraction with ELSSI, the job notification letter contains the command line to reproduce the same job.
