cleos -j missing from multiple commands

We can divide the cleos sub-commands into: 1) those that are not expected to output a JSON to console; 2) those that always write their output in JSON format; 3) those that should provide the user with an option (via the -j flag) to write the output in JSON format.

Within the third category, I have only identified get currency balance as the sub-command that doesn't provide a -j flag when it should.

A common case is to combine -d and -j to see what cleos would send across the network. Especially useful for people to see how to use apis and system contract actions.
