propertywatch: Add ignore_start_callback config
Add an optional `ignore_start_callback` config to indicate if the
callback shall be ignored on start.
By default the callbacks in property watch are called on start.
There are cases where we do not want such behavior and only expect
callbacks on property changes.
Add the `ignore_start_callback` so that we could config a watch to not
trigger the start callback.
Tested: Verify the callback is not called if the watch config has
`ignore_start_callback: true`
