Pavel Emelyanov 64baab1b95 Merge 'config: prevent SIGHUP from changing non-liveupdatable parameters' from Andrzej Jackowski 
Before this change, it was possible to change non-liveupdatable config
parameter without process restart. This erroneous behavior not only
contradicts the documentation but is potentially dangerous, as various
components theoretically might not be prepared for a change of
configuration parameter value without a restart. The issue came from
a fact that liveupdatability verification check was skipped for default
configuration parameters (those without its initial values
in configuration file during process start).

This change:
 - Introduce _initialization_completed member in config_file
 - Set _initialization_completed=true when config file is processed on
   server start
 - Verify config_file's initialization status during config update - if
   config_file was initialized, prevent from further changes of
   non-liveupdatable parameters
 - Implement ScyllaRESTAPIClient::get_config() that obtains a current
    value of given configuration parameter via /v2/config REST API
 - Implement test to confirm that only liveupdatable parameters are
    changed when SIGHUP is sent after configuration file change

Function set_initialization_completed() is called only once in main.cc,
and the effect is expected to be visible in all shards, as a side effect
of cfg->broadcast_to_all_shards() that is called shortly after. The same
technique was already used for enable_3_1_0_compatibility_mode() call.

Fixes scylladb/scylladb#5382

No backport - minor fix.

Closes scylladb/scylladb#22655

* github.com:scylladb/scylladb:
