Configurable receiver types to ignore when parsing ports

Lines 107 to 112 in e48373c

	case name == "kubeletstats":
	return nil
	// ignore prometheus receiver as it has no listening endpoint
	case name == "prometheus":
	return nil

Currently, the receivers to skip are hard coded into the singlePortFromConfigEndpoint() function. Instead, we can make this configurable with kubeletstats and prometheus as the default list of receivers to skip.

Hi @kristinapathak can I take a look at this issue, if its not resolved.

[kristinapathak]

Sounds great!

[tania-anand]

@kristinapathak is it okay to add config with name skip_receivers with type as array of strings in config file

[secustor]

This should be part of the Collector CRD.

I suggest ports_ignore_receivers as ports already explains that the config will be used to extract ports.

This is an issue for my team as well. Happy to take it on if @tania-anand has gotten bogged down with something else.
