Replace fixed resource names with unique to release name

[akshay196]

Describe the issue you're facing

Hard-coding the name: into a resource is usually considered to be bad practice. Names should be unique to a release. Fixed name can cause the naming conflict if more than one instance of Paralus are deployed to a same namespace.

Create a helper function to generate unique name similar to this. And use that in place of hard coded name.
