Don't run instance collection on deploy jobs

Don't run instance collection on deploy jobs

The deploy jobs are run on dedicated hosts that don't have the
pre-requisites needed by the lf-infra-publishers (eg, facter,
xmlstarlet, click).  This change adds the contents of the
lf-infra-publish macro except for these post-build scripts:

  - lf-infra-sysstat
  - lf-infra-package-listing
  - lf-infra-capture-instance-metadata

And uses a modified log ship builder (Nexus only, not S3)
with fewer dependencies.
