Andrey Smirnov 33332f4c74 chore: support bootloader emulation in firecracker provisioner
Firecracker launches tries to open VM disk image before every boot,
parses partition table, finds boot partition, tries to read it as FAT32
filesystem, extracts uncompressed kernel from `bzImage` (firecracker
doesn't support `bzImage` yet), extracts initramfs and passes it to
firecracker binary.

This flow allows for extended tests, e.g. testing installer, upgrade and
downgrade tests, etc.

Bootloader emulation is disabled by default for now, can be enabled via
`--with-bootloader-emulation` flag to `osctl cluster create`.
