added debug options to configuration and collection auto-create on document methods 

last time we discussed  debug options in general and and collection auto-create in particular I was told about plan to add it to the console... until this implementation I'd suggest to have debug options added to configuration.this will allow developers to turn it on temporary via "-D" or application.conf file entry

e.g. to resolve
https://github.com/baasbox/baasbox/issues/186

application.conf entry would be

debug.options="autocreateCollection"
