Description

When karaf is started with different ssh port - (8102 for instance)
then newly created instances should automatically increase it's ssh port to avoid conflict.

karaf@root()> instance:list
SSH Port | SSH Host | RMI Registry | RMI Registry Host | RMI Server | RMI Server Host | State   | PID   | Name
--------------------------------------------------------------------------------------------------------------
    8102 |  0.0.0.0 |         1099 |           0.0.0.0 |      44444 |         0.0.0.0 | Started | 32538 | root

karaf@root()> instance:create abc

karaf@root()> instance:list
SSH Port | SSH Host | RMI Registry | RMI Registry Host | RMI Server | RMI Server Host | State   | PID   | Name
--------------------------------------------------------------------------------------------------------------
    8102 |  0.0.0.0 |         1099 |           0.0.0.0 |      44444 |         0.0.0.0 | Started | 32538 | root
    8102 |  0.0.0.0 |         1100 |           0.0.0.0 |      44445 |         0.0.0.0 | Stopped | 0     | abc

karaf@root()> instance:start abc 

karaf@root()> instance:list
SSH Port | SSH Host | RMI Registry | RMI Registry Host | RMI Server | RMI Server Host | State   | PID   | Name
--------------------------------------------------------------------------------------------------------------
    8102 |  0.0.0.0 |         1099 |           0.0.0.0 |      44444 |         0.0.0.0 | Started | 32538 | root
    8102 |  0.0.0.0 |         1100 |           0.0.0.0 |      44445 |         0.0.0.0 | Started | 781   | abc

Port is automatically increased when creating new child instances.
It should do the same also for the first one

karaf@root()> instance:create abc2
karaf@root()> instance:list
SSH Port | SSH Host | RMI Registry | RMI Registry Host | RMI Server | RMI Server Host | State   | PID   | Name
--------------------------------------------------------------------------------------------------------------
    8102 |  0.0.0.0 |         1099 |           0.0.0.0 |      44444 |         0.0.0.0 | Started | 32538 | root
    8102 |  0.0.0.0 |         1100 |           0.0.0.0 |      44445 |         0.0.0.0 | Started | 781   | abc
    8103 |  0.0.0.0 |         1101 |           0.0.0.0 |      44446 |         0.0.0.0 | Stopped | 0     | abc2
