These are old Go releases that were stopped being updated in 2018 - mid
2019:

https://golang.org/doc/devel/release.html#go1.9
https://golang.org/doc/devel/release.html#go1.10
https://golang.org/doc/devel/release.html#go1.11

and that are not used by any in-tree SR or component.

Don't drop Go1.12 and Go1.13 yet: they are too outdated and no longer
supported, but those Go releases are still in use by the following
slapos software:

Go1.12: Caddy, GitLab, Grafana
Go1.13: RepMan, Restic

The maintainers of those software are advised to upgrade to Go1.14 due
to at least recent security fixes in net/http package.

Go1.10 is outdated by today as it was last updated in Jan 2019:

	https://golang.org/doc/devel/release.html#go1.10

Go1.14 is current oldstable - i.e. it is still supported and mature.

As currently no in-tree SR or component use gowork's default, the switch
should not introduce any breakage.

Going Go1.14.3 -> Go1.14.9 brings in many compiler and runtime fixes,
including security fixes to package net/http:
