Adding Validation for Flag Inputs

[so-sahu]

Description

We need to add validation to block negative or zero intervals for the flag inputs. Currently, users can set intervals to zero, which may not be a desirable option. We should define the lowest value that users can set and ensure that intervals are within acceptable ranges.

Proposed Solution

• Add validation checks to ensure that intervals are not negative or zero.
• Define the lowest acceptable value for intervals and enforce this limit.

The https://pkg.go.dev/github.com/go-playground/validator/v10 library can be considered for this use case.

Expected Behavior

Users should not be able to set intervals to negative or zero values. The system should validate input intervals and reject values that do not meet the defined criteria.

Additional Context

This enhancement will help improve the reliability and usability of the flag inputs by ensuring that intervals are set to valid and meaningful values.
