[LU-9393] Enhance setstripe options for components

Description

In current implementation of PFL component creation API, the setstripe options are inheritable, which means the next component will take all setstripe options appeared in previous components. This poses a problem that there is no way of creating a component with default options, unless it's in the first component in the lfs setstripe command.

Per discussion with Andreas, a new setstripe option --parent is required to explicitly indicate the component will use default stripe from parent.
