[PATCH] Add changes to support providing time configs in milliseconds

[AmilaSamith]

Purpose

This change allows time configuration values to be provided in milliseconds, with support for specifying the time in decimal seconds

Fixes:wso2/product-micro-integrator#3690

Goals

To allow definition of time out configs in milliseconds.

Approach

This change allows time configuration values to be provided in milliseconds by supporting for specifying them in decimal format (e.g., 1500 milliseconds can be expressed as 1.5 seconds). This offers more flexibility when configuring time durations. This approach was designed considering the backward compatibility. Any value defined in seconds will be converted to milliseconds and used in backend. No changes are required for current setups, ensuring seamless transition to the new format.
