"IP Protocol" should be manfatory field when user creates security group for "Other protocol"

[Radoslaw Smigielski]

Repro steps:

1. Create new Security Group
2. Create new rule for that security group:
     Rule: Other ProtocolDanger: There was an error submitting the form. Please try again.
     Description: Empty
     Direction: Ingress
     IP Protocol: Leave Empty
     Remote CIDR
     CIDR: 0.0.0.0/0 or ::/0

Error popup is show with the message:
"Danger: There was an error submitting the form. Please try again."

If user would specify -1 as a IP protocol, rule is being created.

Expected behaviour:
"IP Protocol" field should be marked as mandatory.
