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

build/ops: refrain from installing/using lsb_release in install-deps.sh
Unfortunately the mapping between release number and codename (which is only
relevant for Debian and Ubuntu btw) is not available from /etc/os-release.
In that one respect, lsb_release was "better".
However, when I weigh the advantages of obtaining that mapping from an external
tool, with the (substantial) risk that the external dependency might cause
trouble on one or more supported distros (to say nothing of the non- or
semi-/pseudo-supported ones), against the work involved in maintaining a
hard-coded mapping (negligible), the needle on my scale immediately swings
toward eliminating the dependency.
Also, I see this commit as part of the longer-term effort to completely expunge
lsb_release from our codebase. See git log --grep lsb_release.
For another example of an external distro-detection tool (albeit one that was
included in Python 2) gone awry, see http://tracker.ceph.com/issues/18163.

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.
