mon: OSDMonitor: only share osdmap with up OSDs

Try to share the map with a randomly picked OSD; if the picked monitor is
not 'up', then try to find the nearest 'up' OSD in the map by doing a
backward and a forward linear search on the map -- this would be O(n) in
the worst case scenario, as we only do a single iteration starting on the
picked position, incrementing and decrementing two different iterators
until we find an appropriate OSD or we exhaust the map.

Fixes: #3629
Backport: bobtail

rbd: support plain/json/xml output formatting

This patch renames the --format option to --image-format, for
specifying the RBD image format, and uses --format to specify the
output formatting (to be consistent with the other ceph tools). To
avoid breaking backwards compatibility with existing scripts, rbd will
still accept --format [1|2] for the image format, but will print a
warning message, noting its use is deprecated.

The rbd subcommands that support the new --format option are : ls, info, snap
list, children, showmapped, lock list.

rbd: fix long lines

Several >80 characters have crept in recently.
The older ones generally don't have very useful history,
so I'm not worried about obscuring the history any more.

rbd: move Formatter construction to main

Each method that uses a formatter is doing the same thing.
Simplify by constructing and handling errors only once.
Also use a scoped_ptr for easy clean up.

XMLFormatter: fix pretty printing

It used the wrong indentation level and did not add a newline after
closing a section. dump_stream() did not indent at all.

Simplify a little and remove the parameter from print_spaces(). If we just
remove the element from m_sections before calling print_spaces() in
close_section(), the number of elements in m_sections is always the
indentation level.
