warnquota: Do not ignore errors in config file

Currently warnquota ignores unknown variables, or lines we cannot parse
in the config file. This is potentially dangerous as that may result
in errors being missed and warnquota operating differently than
administrator intended. Change warnquota to abort on errors in config
file and provide -I option for ignoring errors for backward
compatibility.
