Enable controller common options without "" when using trema run

[y-higuchi]

Current trema run requires trema controller common options like --name , --logging_level, etc. to be enclosed in quotes with the controller name in order for them to take effect.

$ trema run "./controller --name=NewName" -d

It will be easier to use, if trema run command passed those options to the controller, when common options were given to trema run and enable trema run invocation like:

$ trema run ./controller --name=NewName -d 

Note that simply appending common options found to the end of controllers option arguments may cause problem,
when there are controller specifc options.

$ trema run "./controller -a -b -c -- other arguments" --name=NewName -d

In the above case, --name=NewName probably should be inserted after -c

In the next coming release, controller specific options can be passed after --. Read https://github.com/trema/routing_switch/ example for details.
