sharness test command coverage

[whyrusleeping]

Making this issue to track all CLI commands that need to be tested and conditions

Module	Online Test	Offline Test
object	t0051	t0051
ls	t0045	t0045
cat	t0040	t0040
dht	t0170	N/A
bitswap	t0220	N/A
block		t0050
daemon	t0030	N/A
init	N/A	t0020
add	t0040	t0040
config	t0021	t0021
version		t0010
ping		N/A
diag	t0065, (missing: t0151)	t0151
mount	t0030	N/A
name	t0110	t0100

repo gc	t0080
id		t0010
bootstrap	t0120	t0120
swarm	t0140	N/A
update
commands		t0010

Critically missing:

• ipfs ping

Most of the missing tests are just cases where we test online or offline but not
both.

Ok, I think the table above is roughly uptodate now.

@chriscool, thanks a bunch for that!

[cryptix]

Maybe we should commit this table to the tests folder?

[whyrusleeping]

Might be a good idea. make it the readme.md inside tests

[jbenet]

👍 for readme.

I think these table (or tables) should also include what flags + arg combinations are tested.

If this issue is about adding all the missing sharness tests, maybe it could be broken down into many issues or items.

If it was just about adding the current coverage into a file then it is done since PR #954 has been merged.
