Is your feature request related to a problem? Please describe.

I'm planning to move from statsd-exporter to this statsdreceiver, but I saw some mismatch support on the configuration

Describe the solution you'd like

Do we have a plan to support more configuration like the statsd exporter?

I'd be happy to contribute to enable this configuration

if we compare to the current statsdreceiver configuration:

opentelemetry-collector-contrib/receiver/statsdreceiver/protocol/protocol.go

Lines 34 to 40 in 3380d25

	type HistogramConfig struct {
	MaxSize int32 `mapstructure:"max_size"`
	}
	type SummaryConfig struct {
	Percentiles []float64 `mapstructure:"percentiles"`
	}
