The voxl2 has a split architecture. PX4 runs on a posix platform and a Qurt platform. The two communicate uorb topics back and forth with the muorb module. But each has it's own parameters database and they need to stay in sync with each other. This PR adds support to keep the 2 parameter databases in sync. The main parameters database running on Linux has file system support while the Qurt one does not. The Linux side is considered the primary and the Qurt side is considered the remote.
