strata should handle arguments in a more predictable way

[nerakhon]

After running a sucessful backup to my S3 bucket (I see all the files there) when running show backups the tool panics with no replica and show replica-ids turns out empty.

the command was as follows

strata -b mybucket1 --username= --password= backup --replica-id=first

after sucessful backup

strata -b mybucket1 show replica-ids turns out empty:

strata -b mybucket1 show replica-ids
2016/04/11 19:12:40 Starting strata driver
Replicas with backups in remote storage:
2016/04/11 19:12:40 Driver finished cleanly.

and show backups panics:

OK never mind, I found the source of the problem the option parsing explicitly requires "=" in the strings otherwise the backups and other tasks break. I am re-categorizing the bug as strata should better handle arguments.
