Eugene Nikanorov 14ebdbe774 Make VPNaaS 'InUse' exception more clear
In case IpSecPolicy or IKEPolicy is updated while VPN connection that uses it
is already established, IPsecPolicyInUse or IKEPolicuInUse is raised.
Need to clarify their messages to emphasize that policies can't be updated
because they are used by established connection.
