pybind/mgr/dashboard/.pylintrc: drop xrange from the whitelist
since dashboard is now xrange-free, there is no need to have

cannot be emitted at seeing xrange.

qa/tasks: use next(iter(..)) for accessing first element in a view
in python2, dict.values() and dict.keys() return lists. but in python3,
they return views, which cannot be indexed directly using an integer index.
there are three use cases when we access these views in python3:
1. get the first element
2. get all the elements and then *might* want to access them by index
3. get the first element assuming there is only a single element in
the view
4. iterate thru the view
in the 1st case, we cannot assume the number of elements, so to be
python3 compatible, we should use `next(iter(a_dict))` instead.
in the 2nd case, in this change, the view is materialized using
`list(a_dict)`.
in the 3rd case, we can just continue using the short hand of
```py
(first_element,) = a_dict.keys()
```
to unpack the view. this works in both python2 and python3.
in the 4th case, the existing code works in both python2 and python3, as
both list and view can be iterated using `iter`, and `len` works as
well.

because `librbd/cache/rwl/Types.h` includes `libpmemobj.h`, without this

we cannot assume that we are using `make` as the cmake generatator,
for instance, if ninja is used, `$(MAKE)` won't be substituted by ninja.
so we need to check if Make is used as generator, if that's the case, we
can just use `$(MAKE)` so we can benefit from the job control of `make`,
otherwise, `make` is used, because currently, PMDK uses Makefile to
build.
it's a shorthand for finding "make" or "gmake" (for FreeBSD), and set
the path to the executable and the command to use in the generated
"Makefile" or whatever build script generated by cmake.

cephadm: create /var/run/ceph dir via unit.run, not unit file
The systemd unit file is shared with non-ceph daemons, which (1) don't
need the /var/run directory, and (2) are based on a uid/gid from a
different container image, which means we can't figure out the right
ceph uid/gid from them to set the ownership properly.
Instead, put it in the unit.run file... and only for ceph daemons when
we have the uid/gid we need.

Client: make sure the Finisher's mutex lock not held during it being distructed
The objecter_finisher is already started in Client::Client(), but
in the failure path when initializing and starting the Client object,
we may not get a chance to call the Client::shutdown() to stop the
Finisher thread, which maybe still holding the mutex lock in it. Then
when destrucing the Finisher object the pthread_mutex_destroy() will
fail.
This fix will delay the objecter_finisher thread to start in ::init()
until we're ready to call Client::shutdown on any errors instead.
