* treewide Drop unneeded go 1.12 overrides
* Fix packr to be go module compatible.
I updated to version 2.8.0 which is the latest on master.
Then due to the 2 different sets of go modules which are used, I split
the build into two different derivations, then merged them togethor
using symlinkJoin to have the same output structure as the existing derivation.
* Remove consul dependency on go1.12
I updated the consul version to 1.7.2 and flipped it to building using
modules.
* Remove go1.12 from perkeep.
Update the version to the latest unstable on master.
* Update scaleway-cli to not be pinned to go1.12
Switched the version to 1.20
* Update prometheus-varnish-exporter to not depend on go1.12
* Update lnd to build with go1.12
Updated the version
Forced only building subpackages with main to prevent panics over
multiple modules in one repo
* Remove go1.12 from openshift
Had to update the version to 4.1.0 and do a bit of munging to get this
to work
* Remove go1.12 completely.
These are no longer needed.
* Update bazel-watcher and make it build with go 1.14
