Minio cli odd behavior after using cobra

[harshavardhana]

Doesn't work

> ./minio --tls --key key.pem --cert cert.pem
flag needs an argument: --key

Usage: 
  minio [flags]

 Available Flags:
  -c, --cert="": cert file path
  -h, --help=false: help for minio
  -a, --http-address=":8080": http address
  -k, --key="": key file path
  -s, --storage-type="file": file,inmemory
  -t, --tls=false: enable tls

Works with following styles

./minio --tls -k key.pem -c cert.pem
2015/01/28 17:29:27 Starting HTTP Server on: :8080

 ./minio --tls --key=key.pem --cert=cert.pem
2015/01/28 17:30:07 Starting HTTP Server on: :8080

This is a odd behavior which didn't exist with Codegangsta, i guess the issue is cobra implementation which doesn't honor certain inputs under long form args

Cobra uses pflags, which follows gnu opts syntax more closely. I don't see anywhere in pflags where we can adjust this behavior.

Reverted this.
