FUEL web UI incorrectly validate vcenter cluster names that contain space chars

[Igor Zinovik]

VMware vCenter allows use of space characters in cluster names, e.g. "my dev cluster".
Right now FUEL web UI incorrectly validates such names. Regular expression that check names must be fixed.

217 regex:

219 error: "Invalid clusters list"

BTW it does not allow to specify cluster name that consists of single char, like 'a' or '1'.
Specifying string 'a,b,c' is also not validated.

    Correct RE that validates vCenter cluster names

    - match cluster names that include metachars (!@#$%^&*()_+{}:"<>?)
      e.g. 'cluster No.42'
    - right now cluster names with comma are not supported
    - adjust message a little, while here
