Add the cluster topology in the hosts_file

[fbeneventi]

Currently, the location of the nodes in the room is derived from the hostname encoding.

However, there are situations where this is not possible.

In these cases, a possible solution is to add a special field called LOCATION to the hosts_file. The field contains the location of the node in the custom key/value sequence format.

Example:

# BMC-IP;HOSTNAME;LOCATION;USER;PASSWORD;CUSTOM_OPTIONS
192.168.0.1;node01;rack/01/chassis/01/slot/01;user;pass;-L OPERATOR -R 4 -N 1 -S ./nodexx_sdr-dump

This string will be added as is in the topic after the .../node/<hostname>/ field.
