Currently there are two ways to specify the KRA connector hosts in the CA configuration file:

If there's only one host it has to be specified in the following properties:

ca.connector.KRA.host=kra.example.com
ca.connector.KRA.port=8443

If there are multiple hosts, the host property turns into a list of hosts & ports, and the port property becomes unused:

ca.connector.KRA.host=kra1.example.com:8443 kra2.example.com:8443
ca.connector.KRA.port=8443

This mechanism is rather confusing and error prone, and the code has become unnecessarily complex since it has to handle multiple cases and the conversions between them.

To fix the problems, the KRA connector should use the same mechanism regardless of the number of hosts it has, for example:

ca.connector.KRA.hosts=kra1.example.com:8443,kra2.example.com:8443

or alternatively:

ca.connector.KRA.hosts.count=2
ca.connector.KRA.hosts.0.host=kra1.example.com
ca.connector.KRA.hosts.0.port=8443
ca.connector.KRA.hosts.1.host=kra2.example.com
ca.connector.KRA.hosts.1.port=8443

There should be an upgrade script to convert the existing CA configuration file.
