Make table rendering consistent across commands

[herver]

With the updated prettytable-rs from #28 I played a little bit to get a more consistent table output, mainly for enclosure and disks listing.

h3. Current output

• Enclosure listing
  

• Disks listing
  

h4. Possible new output format

• Enclosure listing
  

• Disks listing
  

What is your feeling on this ?

I feel it is beautiful :)
It looks way better, thanks to work on this.

Can we have a PR with these changes?

And plus you managed to sort the SLOT, which is a big plus :)

But need to be sure the sort in the slots really match the DISK and MAP, that was very hard for me to make, and I gave up in the end.

Comparing the images before/after, looks like the Array slot isn't right anymore with the "sort", would be interesting if you could double check it.

Example to check:
Before sort:
dev: dev/sg20 map: /dev/sdu slot: 18
After sort:
dev: dev/sg20 map: /dev/sdu slot: 20

I haven't explicitly sorted anything...
For the array -> slot mapping, the screenshot comes from a different model of JBOD, that didn't enumerate in the same order, but I will make sure it doesn't change :)

@herver feel free to open an MR with these changes, it really looks better than what is presented right now. I personally liked a lot :)
