Pavlo Yadvichuk 11c2e9ee3d [barefoot]: Allow configuration of platform-specific interfaces used for internal purposes (#2631)
- Why it is required
since SONiC master switches ifupdown package to the new implementation (ifupdown2), it is required to change the configuration of a platform-specific interface for wedge100bf_32x and wedge100bf_65x platforms (bc of ifupdown2 doesn't support auto mode for inet6 protocol).

Also, need to make some refactoring and remove if platform == smth then.. from the system level scripts.

- What I did

removed customization of /usr/bin/interfaces-config.sh
explicitly created directory /etc/network/interfaces.d
added "source" to the /etc/network/interfaces generation template (to include platform-specific interfaces processing)
added platform-specific interfaces config itself (for wedge100bf_32x and wedge100bf_65x)
fixed testcase in sonic-config-engine
- How to verify it

build image for wedge100bf_32x
perform sudo config reload -y on new installation
check the correct configuration of usb0 interface
- Description for the changelog

Allow configuration of platform-specific interfaces
