By default, per-table-per-shard metrics reporting is turned off, and the
aggregated version of the metrics (per-table-per-node) will be turned
on.
There could be a situation where a user with an excessive number of
tables would suffer from performance issues, both from the network and
the metrics collection server.
This patch adds a config option, enable_node_table_metrics, which allows
users to turn off per-table metrics reporting altogether.
For example, when running Scylla with the command line argument
'--enable-node-aggregated-table_metrics 0' per-table metrics will not be reported.
