Improve performance measurement and counters

[rysavy-ondrej]

Implement a comprehensive set of counters to deal with various performance characteristics of the builder pipeline.

Provide Web-based performance monitor

[rysavy-ondrej]

Each component of the processing pipeline can support counters. The design pattern is that the class defines Counters class that is accepted as an optional constructor parameter. If it is provided, it is used by the component to provide actual counters. For instance:

class Component
{
  Counters? _counters = null;
  ILogger? _logger = null;
  public Component( Counters counters, ILogger logger)
  {
    _counters = counters;
    _logger = logger;
  }

  int Process (int value)
  {
     if (_counters) _counters.ProcessedItems++;
     return value * value;
  }

  public class Counters
  {
     int ProcessedItems;
  }
}

Performance counter implemented using dotnet-counters.

Todo: enable remote monitoring.

dotnet-counter is acceptable solution for performance monitoring,
