Juju should add new machine after version sorting bundle machines

[Nobuto Murata]

$ juju version
2.3.5-xenial-amd64

When deploying a bundle, Juju adds bundle machines from 0, 1, 10, 11, ..., 2, 20. Considering that Juju also supports "--map-machines existing,X=Y" for re-running `juju deploy`. It would be definitely straightforward if Juju adds bundle machines after sorting numerics naturally (version sort). So that we don't need to pass "X=Y" less frequently. See an actual and expected outputs below.

[actual]

$ juju deploy ./bundle.yaml
...
- add new machine 0
- add new machine 1
- add new machine 2 (bundle machine 10)
- add new machine 3 (bundle machine 11)
- add new machine 4 (bundle machine 12)
- add new machine 5 (bundle machine 13)
- add new machine 6 (bundle machine 14)
- add new machine 7 (bundle machine 15)
- add new machine 8 (bundle machine 16)
- add new machine 9 (bundle machine 17)
- add new machine 10 (bundle machine 18)
- add new machine 11 (bundle machine 19)
- add new machine 12 (bundle machine 2)
- add new machine 13 (bundle machine 20)
- add new machine 14 (bundle machine 21)
- add new machine 15 (bundle machine 22)
- add new machine 16 (bundle machine 3)
- add new machine 17 (bundle machine 4)
- add new machine 18 (bundle machine 5)
- add new machine 19 (bundle machine 6)
- add new machine 20 (bundle machine 7)
- add new machine 21 (bundle machine 8)
- add new machine 22 (bundle machine 9)

[expected]

$ juju deploy ./bundle.yaml
...
- add new machine 0
- add new machine 1
- add new machine 2 (bundle machine 2)
- add new machine 3 (bundle machine 3)
- add new machine 4 (bundle machine 4)
- add new machine 5 (bundle machine 5)
- add new machine 6 (bundle machine 6)
- add new machine 7 (bundle machine 7)
- add new machine 8 (bundle machine 8)
- add new machine 9 (bundle machine 9)
- add new machine 10 (bundle machine 10)
- add new machine 11 (bundle machine 11)
- add new machine 12 (bundle machine 12)
- add new machine 13 (bundle machine 13)
- add new machine 14 (bundle machine 14)
- add new machine 15 (bundle machine 15)
- add new machine 16 (bundle machine 16)
- add new machine 17 (bundle machine 17)
- add new machine 18 (bundle machine 18)
- add new machine 19 (bundle machine 19)
- add new machine 20 (bundle machine 20)
- add new machine 21 (bundle machine 21)
- add new machine 22 (bundle machine 22)

I *think* this is just changing an alphabetical sort into a numeric lexical sort, and we have that function somewhere.

utils.SortStringsNaturally()
(elsewhere it is called 'naturalsort')

and I got it from Martin Pool:

Yet another thing to move out of utils.

Does this make sense to have in a juju/collections package?

I'd just make a github.com/juju/naturalsort.Sort package.
