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.

before this change, we fails to detect std::filesystem with clang++,

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

doc: explain how to mkdir under .snap

Prior to this change, the CephFS snapshot instructions were not clear
whether users should "mkdir" the ".snap" directory or not.

Update the documentation to clarify that users should make a directory
under .snap with a name of their choice.

Thanks to John Spray <jspray@redhat.com> on ceph-users for this
information.
