Remove ejconlon from maintainership

[ejconlon]

I no longer have commit access to ekg, so I can't maintain it. Also removed packages with 0 reverse deps.

@ejconlon : You still have Hackage maintainership, which is all that is needed to publish revisions and releases: https://hackage.haskell.org/package/ekg/maintainers

But it seems you want to step back from maintainership.

Removing simply packages from build-constraints.yaml isn't the way to do this, as you can see from the errors CI reports:

ekg-core (not present) depended on by:

• monad-metrics-0.2.2.1 (>=0.1.0.1 && < 0.2). Matt Parsons [email protected] @parsonsmatt. Used by: library
• wai-middleware-metrics-0.2.4 (>=0.1). Sebastian de Bellefon [email protected] @Helkafen. Used by: library

Instead please move the package to the section "Abandoned packages".

stackage/build-constraints.yaml

Lines 5851 to 5858 in d98690d

	# If you stop maintaining a package (either just on stackage, or
	# completely), you can move it here. It will be disabled if it
	# starts causing problems.
	#
	# See #1056/closed
	#
	# When disabling one of these packages, move it to "Removed packages".
	"Abandoned packages":

Is there a new maintainer for ekg etc.?

I would recommend moving to a different maintained instead of abandoned packages if possible, as we will have to drop the package and all those that depend on it if it is abandoned and Stack(age) encounters issues when building it.

[ejconlon]

Moved to abandoned. Possibly can add to @23Skidoo packages but I think the package is overall infrequently maintained. It would be better to migrate to something else, I think. In any case, I haven't used it in years, so I'm not a good maintainer.

Thank you!
