A config option value is reported as 'text' type and contains
a string as it would looks like in json config.
The table is UPDATE-able. Only the 'value' columnt can be set
and the value accepted must be string. It will be converted into
the option type automatically, however in current implementation
is't not 100% precise -- conversion is lexicographical cast which
only works for simple types. However, liveupdate-able values are
only of those types, so it works in supported cases.

Contains all version related information (`nodetool version` and more).
Example printout:
(cqlsh) select * from system.versions;
key | build_id | build_mode | version
-------+------------------------------------------+------------+-------------------------------
local | aaecce2f5068b0160efd04a09b0e28e100b9cd9e | dev | 4.6.dev-0.20211021.0d744fd3fa
Loosly contains the equivalent of the `nodetool info` command, with some
notable differences:
* Protocol server related information is in `system.protocol_servers`;
* Information about memory, memtable and cache is reformatted to be
tailored to scylla: C* specific terminology and metrics are dropped;
* Information that doesn't change and is already in `system.local` is
not contained;
* Added trace-probability too (`nodetool gettraceprobability`);
TODO(follow-up): exceptions.
Lists all the client protocol server and their status. Example output:
(cqlsh) select * from system.protocol_servers;
name | is_running | listen_addresses | protocol | protocol_version
------------------+------------+---------------------------------------+----------+------------------
native transport | True | ['127.0.0.1:9042', '127.0.0.1:19042'] | cql | 3.3.1
alternator | False | [] | dynamodb |
rpc | False | [] | thrift | 20.1.0
redis | False | [] | redis |
This prints the equivalent of `nodetool statusbinary` and the "Thrift
active" and "Native Transport active" fields from the `nodetool info`
output with some additional information:
* It contains alternator and redis status;
* It contains the protocol version;
* It contains the listen addresses (if respective server is running);
