Add Memory Maps telemetry device

https://github.com/elastic/elasticsearch/issues/119652 shows we need a new telemetry device that would periodically report the amount of memory maps, i.e. wc -l /proc/<ES PID>/maps.

Crucially, such telemetry device should support a setup where benchmark is done using --pipeline=benchmark-only and Elasticsearch is started/stopped with esrally start/stop.
