as a C++ project, we should depends on g++. actually, GCC-7 is able to
support C++17. but we use C++17 features extensively, and have been
running into GCC bugs every now and then. so would be ideal if we can
use newer GCC if possible.
we've dropped the support of ubuntu/xenial. while on ubuntu/bionic, only
GCC-7.4 is available. so let's require g++ (>= 7) then.

tools/setup-virtualenv.sh: do not default to python2.7
This commit changes the script's behavior when run without a --python option.
Before, we were running virtualenv with "--python python2.7" in that case.
That is not a reasonable default in September 2019, given that Python 2 EOL is
coming on January 1, 2020. Also, it breaks setup-virtualenv.sh in py3-only
environments.
With this patch, the script will not pass any "--python" option to virtualenv
(i.e., it will let virtualenv do whatever it thinks is best) in this case.
classic OSD started to use single-pg peering ops since ce05c172, and it
switched over to these ops since octopus. and it's assumed that
crimson-osd won't be GA until octopus+2 release, so it's not needed to
support pre-octopus releases.

Create new action class for do_du()'s args.paths and push the code that
handles arguments for do_du() in there. The intention is to keep only
the code that does some disk usage stuff in do_du().

cephfs-shell: refactor do_du()
Improve code's readability and keep all paths as bytes.
Specifically, define a function within do do_du() to simplify the code
that handles recursion, rename args.dirs to args.paths, get rid of
dir_passed and use args.paths directly instead, change the default
value of args.dirs to a list with one member that contains current
working directory, rewrite the docstring, and few more similar changes.

test_cephfs_shell: add a method to get command output
Let run_cephfs_shell_cmd() return the object instead of output in string
format so that stderr, return value, etc. of the command executed
remain available. And add a new method that returns only output of the
CephFS shell command executed.

Convert cmd to string if it is passed as list to

elsewhere, in tests, command to be executed must be a list of arguments
rather than string of arguments separated by spaces.

mds: recall caps from quiescent sessions
This introduces two new config options [1,2] that dictate when a session
is considered quiescent by the MDS. (Options are documented fully in
options.cc.) When a session is quiescent, the MDS will preemptively
recall caps to reduce the outstanding capabilities which optimizes for
reducing work during failover.
