cmake: fix std::filesystem detection and extract sanitizer detection into its own module

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

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.

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.

we could create a mini project to build a shared library, and use
try_compile() to test if the found gperftools is compiled with -fPIC.
but as we are targeting mostly xenial when enabling
WITH_STATIC_LIBSTDCXX, and google-perftools on xenial by default
is built without -fPIC. so let's keep it simple.

do not build ceph_test_admin_socket_output if we are not able to find
the library for std::experimental::filesystem . it is a workaround of
https://reviews.freebsd.org/D10840 where FreeBSD 11.2 does not ship
libc++experimental.a .

the cmake config provided by fmt-devel-3.0.2 does not offer fmt::fmt target,
so we need to offer a Findfmt.cmake to do this.

and remove src/test/gtest-parallel submodule, because gtest-parallel is
only useful for running tests. and not all end-users are interested in
running test not to mention running them in parallel. so, to avoid
including gtest-parallel scripts in the dist tarball. it'd be better to
make it optional, and an external project.

Unittests are run sequentially and could take a long while to run.
This commit is about using gtest-parallel on some of them which are
known to be very slow due to this sequentiality.
To enable the parallel features, the 'parallel' argument just have to be
added to the add_ceph_unittest() call like in :
-add_ceph_unittest(unittest_throttle)
+add_ceph_unittest(unittest_throttle parallel)
This commit impact the following tests :
Test name Before After (in seconds)
unittest_erasure_code_shec_all: 212 43
unittest_throttle 15 5
unittest_crush 9 6
unittest_rbd_mirror 79 21
Total 315 75
This commit saves 240 seconds (4 minutes) per build.
Note it exist several other long tests but can't be parallelized since
there is explicit dependencies in the order to run the subtests.
Those stay sequential.

in spdk v18.05, libuuid is linked by libspdk_util.a, in which,
it is used by lib/util/uuid.c. and libspdk_vol.a uses the wrapper
function exposed by libspdk_util.a, so update the CMakefile script to
reflect the change.

we should reference liboath by the $name in Find${name}.cmake, also the
$name should be consistent when calling find_package_handle_standard_args().
in this change
* rename Findliboath.cmake to FindOATH.cmake to be consistent with other
find_package() moduless.
* use "OATH" in find_package_handle_standard_args() instead of "oath"
* set the interface properties for OATH::OATH, so the target linking
against it can reference its header directories and libraries automatically.
* remove the stale comment for find_package_handle_standard_args()
* set OATH_INCLUDE_DIRS and OATH_LIBRARIES to follow the convention of
find_package(), even they are not used directly in this project.

we have 'DH_VERBOSE=1' in debian/rules, which instructs debhelper to
pass -DCMAKE_VERBOSE_MAKEFILE=ON to cmake. but the verbose output for
building boost does not really help if something goes wrong while
building the deb packages. if we do want to enable the verbose output,
we can always enable it by passing `-d <N>' to it. see

we should enable them if they are found.
currently, we don't have bzip2 compressor plugin, so it's not detected
in the cmake script. we can always enable it for rocksdb in future.
