## Description of problem:

In RHEV, admin UI rejects FQDNs ending in a digit when creating NFS storage domains

## Version-Release number of selected component (if applicable):

3.4, customer also reports this happening in 3.2

## How reproducible:

always

## Steps to Reproduce:
1. Create an NFS Data Center
2. On storage, create an appropriate NFS share
3. Via DNS create a domain that ends in a digit (ie: foo.example.f7)  Or, just update /etc/hosts so that storage resolves to this name.
4. Try to create a storage domain with foo.example.f7:/<export>

## Actual results:

Attempt to create SD fails ("Error while executing action: Mount path is illegal, please use [IP:/path or FQDN:/path] convention.")

## Expected results:

Create SD as expected, with FQDN ending in a digit

## Additional info:

The workaround is to use the IP address, or short host name (assuming domain is in resolv.conf search path). 

While this is an unusual domain name, It is to my knowledge valid [1], and I can't see any logical reason why it should be excluded.
