SAN Topology prerequisites

This feature requires installation of Graphviz and its prerequisites.

Linux RedHat, CentOS, XoruX Virtual Appliance with Internet repo access
```
yum install graphviz perl-Want
```
Linux Ubuntu, Debian with Internet repo access
```
apt-get install graphviz 
```
Note libmodule-want-perl available on Debian does not contain necessary libraries (perhaps is too old) therefore install manually CPAN perl module Want.
```
tar xvfz Want-0.29.tar.gz 
cd Want-0.29/
perl Makefile
make 
make test
make install
```
If you face error "Undefined subroutine &Set::Array::want..." then make surre libmodule-want-perl module does not exist in the system
SuSE with Internet repo access
```
zypper install graphviz perl-Want
```
Linux CentOS 7, RHEL 7, XoruX Virtual Appliance without Internet repo access
