Thanks @ashish111333 for the PR!

Make sure to run

helm template release-name .

from the dragonfly directory to check the chart is rendering as expected. I'm currently getting the following error:

Error: values don't meet the specifications of the schema(s) in the following chart(s):
dragonfly:
- serviceMonitor: Invalid type. Expected: boolean, given: object

Can you check it out?

@petar-cvit fixed, can you review it now.
