This is a milestone in the CephFS shell project. QA testing is still in the
works and will be merged separately. Installation code via CMake will also be
written in another PR.

doc: add cephfs-shell to cephfs doc index
cephfs-shell: add new CephFS shell
Reviewed-by: Patrick Donnelly <pdonnell@redhat.com>
The CephFS shell is an alternative client to access CephFS without mounting in
the usual way. The shell provides commands to interactively access the file
system, like put, ls, chmod, etc.

qa/suites/fs: add python3-cephfs to packages
the default set of packages to install is in
$suite/qa/packages/packages.yaml . see get_package_list() in
teuthology/teuthology/task/install/__init__.py for how we prepare a
package list for install task.
for running python3 tests in
fs/basic_functional/tasks/volume-client, we need to install
python3-cephfs. please note that,
_package_override() in teuthology/teutholoy/task/install/rpm.py will
take care of the different naming on centos/rhel, where the python3
packages are named python34-*.
task.install.rpm installs packages listed in
$suites/qa/packages/packages.yaml, the packge list applies to the
upgrade tests also. but we don't have python3 bindings packages in jewel
-- they were introduced in kraken.
test: use death_test_style="threadsafe" for Mutex.NormalAsserts
use threadsafe for running the Mutex assert test to run the test from
beginning to avoid the hang. this test overrides the symbol of
ceph::__ceph_assert_fail() with a local one offered by the application
links against libceph-common. but we intentionally forbid this behavior:
we do not allow libceph-common to reference the symbols exposed from
application with the same name. see http://tracker.ceph.com/issues/25154

cmake: require 4.0.0 <= libfmt-dev < 5.0.0
FMT_VERSION is now living in fmt/core.h in libfmt >= 5.0, so we cannot
parse fmt/format.h for libfmt's version anymore. also we don't need
Findfmt.cmake now. because libfmt-dev 4.0 and up is required by seastar,
also it's libfmt-dev 3.x's cmake module which fails to offer fmt::fmt
target. in other words, it's safe to drop libfmt 3.x support. but 5.0.0
is not compatible with seastar, we will have failures like:

so, we should build libfmt even if we have libfmt-dev 5.x

cmake: extract sanitizer detection out
also, we don't need to pass '-lasan' or '-ltsan' to linker. it's
suggested to use the "-fsanitize=${sanitizer}".
please note, this module is compatible with the one used in seastar on
purpose, as seastar is included in ceph using add_subdirectory(), and it
in turn add its own cmake modules directory using list(APPEND ...), so
cmake/modules/FindSantitizers.cmake is prefered over
src/seastar/cmake/FindSantitizers.cmake.

cmake: fix StdFilesystem detection
before this change, we fails to detect std::filesystem with clang++,
because the cmake project created by try_compile() only expands
following options passed from its caller:
- COMPILE_DEFINITIONS
- INCLUDE_DIRECTORIES
- LINK_DIRECTORIES
- LINK_LIBRARIES
which do not include CMAKE_CXX_FLAGS, so either we need to (ab)use
COMPILE_DEFINITIONS for passing -std=c++17, or we can change the
CMAKE_CXX_FLAGS in the parent env, as it turns out the created cmake
project does inherit this flag from current project. in this change,
we use the COMPILE_DEFINITIONS approach: simpler this way. and we
can drop it once cmake 3.8 is required.

mgr/devicehealth: add helpers to life_expectancy_response()
- if mark_out_threshold is met we write to log.warn instead of raising a
health warning.
- check that OSD is 'in' before calling mark_out().
- raise a health warning in case OSD is marked 'out' but still has PGs
attached to it.
- cast thresholds default values to string.
- add SCSI multipath support to health warning message.
- change health warning message.
