[COMMON] Use "" instead of {} as a default value to avoid warning
After we upgraded our helm version we started getting below issues
with emails:
Warning: Merging destination map for chart 'curator'.
Overwriting table item 'image', with non table value:
onap/sdnc-image:1.8.2
To fix this let's just use "" instead of () for our daily operations.
