it'd be easier for the static analyzer (like GCC), to reason about if
a variable is initialized before being used.
this change also helps to improve the readability, and to silence the
false alarm like:

replace strict_iecstrtoll(const char *str,..) with
strict_iecstrtoll(std::string_view, ..). which is more convenient.
and both of them share the same implementation:
strict_iec_cast<uint64_t>(str, err);
so they are interchangeable.
Signed-off-by: Kefu Chai <kchai@redhat.com>
strict_sistrtoll() is but an alias of strict_si_cast<uint64_t>(..),
let's just drop the former. there are way too many thin wrappers in
strtol.{h,cc}. they don't offer lots of benefit to us.

they are but proxies to strict_strto*(string_view, ...). and their
callers can just call the latter without any change. so drop these
proxies.

this variant is better than strict_si_cast(const char*), because:
* we can just pass std::string to it, as std::string_view can be
constructed from a std::string implicitly
* strict_si_cast(std::string_view, ..) is the underlying
implementation of strict_si_cast(const char*,..), so less
indirection helps with the readability.

because fmt is packaged in EPEL, while librados is packaged
in RHEL, so we cannot have fmt as a runtime dependency of librados.
to address this issue, we should compile librados either with static library
or with header-only library of fmt. but because the fedora packaging
guideline does no encourage us to package static libraries, and it would
be complicated to package both static and dynamic library for fmt.
the simpler solution would be to compile Ceph with the header-only
version of fmt.
in this change, we compile ceph with the header-only version of fmt
on RHEL to address the runtime dependency issue.

in this change:
* an interface library named "fmt-header-only" is introduced. it brings
the support to the header only fmt library.
* fmt::fmt is renamed to fmt
* an option named "WITH_FMT_HEADER_ONLY" is introduced
* fmt::fmt is an alias of "fmt-header-only" if "WITH_FMT_HEADER_ONLY"
is "ON", and an alias of "fmt" otherwise.
because fmt is packaged in EPEL, while librados is packaged
in RHEL, so we cannot have fmt as a runtime dependency of librados.
to address this issue an option "WITH_FMT_HEADER_ONLY" is introduced, so
that we can enable it when building Ceph with the header version of fmt.
and the built packages won't have runtime dependency of fmt.

We don't need to run an extra command (mgr module ls) to obtain the mgr
modules list since we already have this information in the mgr_map.
This workflow is already done for the monitoring stack or for configuring
the iscsi integration within the dashboard (during creation) via the
config_dashboard method.
The mgr_map is mocked in the tests with the dashboard module enabled so we
don't need _mon_command_mock_mgr_module_ls anymore.
