Introduce expression filters for events

[VaibhavPage]

Is your feature request related to a problem? Please describe.
The sensor event dependencies currently have data, context, and time filters which offer a limited set of filtering capabilities. Introduce a more powerful filter where the user can define an expression/s that are flexible enough to address every usecase.

Describe the solution you'd like
Add a new filter called exprFilters

exprFilters:
    - fields:
        - path: height
          name: field1
          type: number
        - path: weight
          name: field2
          type: number
      expr: (field2 / (field1 * field1)) > 20
    - fields:
        - path: weight
          name: field1
          type: number
      expr: field1 > 70
      name: filter2
  circuit: filter1 || filter2
