since we do not rely on FMT_DEPRECATED_OSTREAM to define the
fmt::formatter for us anymore, let's stop defining `FMT_DEPRECATED_OSTREAM`.
in this change,
* utils: drop the range formatters in to_string.hh and to_string.c, as
we don't use them anymore. and the tests for them in
test/boost/string_format_test.cc are removed accordingly.
* utils: use fmt to print chunk_vector and small_vector. as
we are not able to print the elements using operator<< anymore
after switching to {fmt} formatters.
* test/boost: specialize fmt::details::is_std_string_like<bytes>
due to a bug in {fmt} v9, {fmt} fails to format a range whose
element type is `basic_sstring<uint8_t>`, as it considers it
as a string-like type, but `basic_sstring<uint8_t>`'s char type
is signed char, not char. this issue does not exist in {fmt} v10,
so, in this change, we add a workaround to explicitly specialize
the type trait to assure that {fmt} format this type using its
`fmt::formatter` specialization instead of trying to format it
as a string. also, {fmt}'s generic ranges formatter calls the
pair formatter's `set_brackets()` and `set_separator()` methods
when printing the range, but operator<< based formatter does not
provide these method, we have to include this change in the change
switching to {fmt}, otherwise the change specializing
`fmt::details::is_std_string_like<bytes>` won't compile.
* test/boost: in tests, we use `BOOST_REQUIRE_EQUAL()` and its friends
for comparing values. but without the operator<< based formatters,
Boost.Test would not be able to print them. after removing
the homebrew formatters, we need to use the generic
`boost_test_print_type()` helper to do this job. so we are
including `test_utils.hh` in tests so that we can print
the formattable types.
* treewide: add "#include "utils/to_string.hh" where
`fmt::formatter<optional<>>` is used.
* configure.py: do not define FMT_DEPRECATED_OSTREAM
* cmake: do not define FMT_DEPRECATED_OSTREAM

before this change, we rely on the default-generated fmt::formatter
created from operator<<, but fmt v10 dropped the default-generated
formatter.
in this change, we include `fmt/ranges.h` and/or `fmt/std.h`
for formatting the container types, like vector, map
optional and variant using {fmt} instead of the homebrew
formatter based on operator<<.
with this change, the changes adding fmt::formatter and
the changes using ostream formatter explicitly, we are
allowed to drop `FMT_DEPRECATED_OSTREAM` macro.

In a follow-up patch abort_source will be used
inside those methods. Current pattern is that abort_source
is passed everywhere as non const so it needs to be
executed in non const context.

Fixes#10099
Adds the com.scylladb.auth.CertificateAuthenticator type. If set as authenticator,
will extract roles from TLS authentication certificate (not wire cert - those are
server side) subject, based on configurable regex.
Example:
scylla.yaml:
authenticator: com.scylladb.auth.CertificateAuthenticator
auth_superuser_name: <name>
auth_certificate_role_queries:
- source: SUBJECT
query: CN=([^,\s]+)
client_encryption_options:
enabled: True
certificate: <server cert>
keyfile: <server key>
truststore: <shared trust>
require_client_auth: True
In a client, then use a certificate signed with the <shared trust>
store as auth cert, with the common name <name>. I.e. for cqlsh
set "usercert" and "userkey" to these certificate files.
No user/password needs to be sent, but role will be picked up
from auth certificate. If none is present, the transport will
reject the connection. If the certificate subject does not
contain a recongnized role name (from config or set in tables)
the authenticator mechanism will reject it.
Otherwise, connection becomes the role described.
