Dmitriy Rabotyagov 4715b470f9 Always build wheels by default
Due to some corner cases that are possible with currnet logic,
it was decided to simply it and always build wheel regardless of host
count. While runtime might take a bit longer, it's always better for
scaling up to already have wheels prepared.

Closes-Bug: #2004252

# Set the available build targets for all nodes within an environment.
# build targets are grouped based on operating system and CPU
# architecture.
#
# This is the data structure used to determine the build host.
# venv_build_targets:
# {
# ansible_facts['distribution_version']: {
# ansible_facts['architecture']: inventory_hostname
# }
# }
#
# Auto generation process:
# * The automatic build targets will iterate over the group name
# "repo_all" and if any target is found it will catagorize it
# using the distro and cpu architecture criteria.
# * If no group named "repo_all" is found the current inventory
# hostname will be used as the only available build target.
# * If no build target is found for matching the distro and cpu
# criteria of the active inventory item, the generator will fall
# back to using the active inventory host as the build target.
#
# NOTE: (cloudnull): While there may be multiple inventory items
# that match a single distro and CPU architecture
# type, only one build target will ever be used.
# To make more than one build target effective,
# deployers should be using a shared file system
# for the repo servers.
