[SDNC] Provide hardcoded aaiclient.properties file via helm

Currently /opt/onap/ccsdk/data/properties directory with its
configfiles is saved in sdnc image and not provided via helm.
File "aaiclient.properties" stored there appears to be used for
determining AAI URI by directed graphs. In this patch,
aaiclient.properties provided by configmap is added to this directory,
with still being passed to previous one. This helps with following
error you could see in karaf logs:
