added cli controller that parses all logs to backend

tag 'log' has to be set in web for db table updatescript
overview for parsed logs from web

shows errors, accessdenied and notfound logs in grid and form view
renamed variables and filenames for log controllers and check log updateTag before parse
moved controller to action debug
name fix for log updatescript
optimized parse for log files
removed renderer for spaces and use pre tags for output
added debug logs as resource so its always reachable for admins
deleted cli controller for parsing log files
added possibility to parse log files manually, delete all log files and delete all shown log files in db
added check for useragent and session in parse logs action
if logged in user is admin exception will be shown
save files to db with model import, better for performance and speed of saving
