Lotus devnet image #29

	name: Lotus devnet image

	# Only build and publish this image on demand.
	# The compilation adds significant overhead to the CI and it is not supposed
	# to change very often (roughly once per per network upgrade; ~3-4 months).
	# This image is used in the local devnet for both the lotus-node and the lotus-miner.
