CLOUDSTACK-6512:IAM - Not able to list shared networks in the Vm
deployment flow. This commit is to revert
ec5ee761d98c67c7da2ea70b623d4a9f3da966b5 to still use old logic for
listNetworks to keep old behavior instead of new IAM model.
In 4.3, SSL was turned off by default.
However, for SSVM, the value from configuration server overrides the default in Config.java. Work around is to change in global properties.

Local testing, checking a fresh install has the above property false by default.
