f90dbf9b77 refactor(metrics): use prometheus_metrics_enabled for configuration 
As agreed upon during review, use this name to get started. If more
backends were to be added, the configuration structure will be updated.

5c237a07dc refactor(metrics): make to_text get the application state 
As falco may update its state at any time and thus its inspectors objects,
keeping pointers to them may end up in using dangling values.

Therefore, use the state of the application when requesting metrics.

Optimizations such as caching of mostly static values will be done in
a follow up patch.

e50d647dc9 refactor(configuration): move webserver items in own struct 
This makes things easier to pass around like when starting the
web server.

This has the added benefit of simplifying further extension such as
making the metrics endpoint name configurable without adding yet another
parameter to the start function.

memory_used_host -> host_memory_used_kb (or host_memory_used_mb)
procs_running_host -> host_procs_running
open_fds_host -> host_open_fds

memory_rss -> memory_rss_kb (or memory_rss_mb)
memory_pss -> memory_pss_kb (or memory_pss_mb)
