This is for all entities that have a uniquely identifiable via a UUID.
Currently the interface only contains a single function, GenUUID(),
that should generate a new UUID via a random source (`rand.Rand`).
NB: Partitions are uniquely identifiable if and only if the layout is
GPT.

All disk.Entitity types now implement Clone() which should return a
deep copy of the same object. Add the Clone() method to the entity
interface. The return type is Entity, but callers can assume it's
safe to convert back to the original type.

Implement the base type of the new entity system, i.e. `Entity`,
for all relevant components:
- PartitionTable
- Partition
- Filesystem

Split up disk.go into smaller more managable pieces: continue
with moving `Filesystem` to its own file.
