[pve-devel] [RFC manager] pveceph: add osd details command

[Aaron Lauterer]

To provide similar output on the CLI as is possible in the GUI/API
regaring OSD details.

By default (output-format=text) a more concise output is shown. Using
json or yaml as output format will print all the available data.

The 'verbose' flag causes json-pretty output to be used.

The functionality is split between the actual function and the output
formatter as not all options/parameters are available in each.

Depends on the OSD Details patches which are not yet applied [0].

RFC because in order to check against the output format and the verbose
flag, the code ended up split between the actual cmdline method and
the formatting function.

The verbose flag is only available in the formatter and the verbose in
the method itself.

If there would be a nicer way to achieve a similar result, I would be
happy to get hints.
