We want to switch to an addrvec. This requires multiple parts:
- switch the Key type to use just the rank
- separate entity_name_t rank
- compat encoding
- graylog field naming has changed (includes name)
- syslog output formatting has changed (includes name)
- LogEntry operator<< modified a bit

Telegraf is a agent for collecting and reporting metrics.
It has multiple inputs and can send data to various outputs like
for example InfluxDB or ElasticSearch.
This module works by using the socket_listener of Telegraf and can
send data over UDP, TCP and a local Unix Socket.

MDS deactivation is now handled by the max_mds parameter. Deprecate
ceph mds deactivate and note it to be removed in a future release.

As dirfrags are now standard in CephFS, remove the machinery for
tracking and enabling this feature.
ceph fs set <fs> allow_dirfrags is now deprecated and prints a warning
message.

With multi-mds now declared stable, allow_multimds now defaults to 1.
Given the max_mds parameter, it is now redundant. Remove it, leaving a
comment placeholder in the features bitmap.
ceph fs set <fs> allow_multimds is now deprecated and prints a warning
message.

JSON cannot express arbitrary binary blobs. Instead of outputting invalid
and unparseable JSON, represent the value of blobs as something like
'<<< binary blob of length 12 >>>'.

This is too complete a rewrite to reasonably break down into small steps,
and even if I could, it would be harder to review that way than to simply
review the new implementation. The semantics of the old one were so weird
that it's harder to reason about the change in behavior than to simply
review the new behavior.
That's my story, at least, and I'm sticking to it!
So, here are the highlights:
- $foo meta expansions are evaluated at get_val() time. This means the
weird bool arguments to set_val specifying whether things were expanded
are removed (they didn't make any sense unless you were thinking about the
old implementation).
- for every option, we track values from any inputs (config, mon,
override). At get_val() time, we pick the highest priority one.
- diff() is rewritten to be simple and to show you all of the above.
- internal interfaces are simplified, and in terms of Option::value_t
whenever possible.
- unit tests simplified somewhat based on the above.
Known issues:
- legacy values get pushed out in select cases. Notably if foo=$bar
and bar is updated, we do not update $foo (there is no dependency
tracking to do this efficiently).

This script is pointless. It is equivalent to the built-in default
behavior, which makes it only useful as a sample for what a location
hook's output should be. The documentation has been updated to provide
that.

This reverts commit 3189ba19a7, reversing
changes made to b7620de020.
Despite the change in json format being positive, the unfortunate side-effect
is that it broke upgrade testing (because the QA framework must handle the
transition of mdsmap["info"] to a list from object) and the ceph-mgr.
