[FAB-17952] Fix test-network to use the latest version of fabric-ca (#195)

To get rid of hard-coded versioning and use the latest version of fabric-ca
in test-network, this patch modifies the existence check logic of
the fabric-ca-client binary in the same way as peer and orderer.

Also, this patch updates addOrg3.sh to use cai <ca_imagetag> option.
