This patch introduces idmapped mounts support for container rootfs. The idmapped mounts support was merged in Linux kernel 5.12 torvalds/linux@7d6beb7. This functionality allows to address chown overhead for containers that use user namespace. The changes are based on experimental patchset published by Mauricio Vásquez #4734. Current version reiplements support of idmapped mounts using Golang.
