This commit fixes#2347 by ensuring that a minimum
size of 1GB is set for all file systems. The only
exception to this is the `/usr` which is set to 2GB,
since this was the only mountpoint that was previously
being checked.
Implement `PartitionTable.ContainsMountpoint` via `entityPath` instead
of `FindFileSystemForMountpoint`; `entityPath` is the more generic
variant of `FindFileSystemForMountpoint` and will work with anything
that implements `Mountable`.

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.

Uses the new interfaces and supports all the different kinds of
filesystem configurations that we added.
Clones the base PartitionTable before modifying it.

Eventually partition.Payload will be an Entity, so we need to use
more generic functions that work on the interfaces.

Starts from an Entity (typically the PartitionTable) and searches for a
target (Mountpoint), returning a slice of all the entities that lead to
the Mountable with the given Mountpoint (in reverse order).

Add a new enumerator method to `PartitioTable` that allows the
caller to visit all entities inside a partition table.

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.

In our model a partition table has a size to represent the disk size.
Also each individual partition has a size, so they both implement the
Sizeable interface.

A `PartitionTable` is a container for one or more instances of
`Partition`, which itself might contain a `Filesystem`.

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: start with
extracting `PartitionTable` and all its methods to a new file.
