Instead of a timeout and complicated decisions about whether the client is

the number of caps we've recalled. This counter is decremented whenever the
client releases caps. If the counter passes a threshold, then we raise the
warning.

Similar reworking is done for the steady-state recall of client caps. Another
release DecayCounter is added so we can tell when the client is not releasing
any more caps.

crush: fix upmap overkill

It appears that OSDMap::maybe_remove_pg_upmaps's sanity checks
are overzealous. With some customized crush rules it is possible
for osdmaptool to generate valid upmaps, but maybe_remove_pg_upmaps
will cancel them.

osd/OSDMap: using std::vector::reserve to reduce memory reallocation

In C++ vectors are dynamic arrays.
Vectors are assigned memory in blocks of contiguous locations.
When the memory allocated for the vector falls short of storing
new elements, a new memory block is allocated to vector and all
elements are copied from the old location to the new location.
This reallocation of elements helps vectors to grow when required.
However, it is a costly operation and time complexity is involved
in this step is linear.
Try to use std::vector::reserve whenever possible if performance
matters.

osd/OSDMap: more improvements to upmap

- add ability of appending a 2nd, 3rd, etc... pair to existing upmaps
  when possible, rather than just continuing to the next PG
- handle the underfull case: we can rm-pg-upmap-items if there exist
  any upmaps which remapped a PG out from an underfull OSD

restful: Fix regression when traversing leaf nodes

The commit 23b6c90 introduced a regression when traversing leaf nodes.
The issue is that it traverses the keys of a `dict` returned by
`nodes_by_id`, not the actual `items` of the node. That resulted in an
500 error because it tried to treat `str` as a `dict` and failed.
