Many code blocks are 4spaced, and they render in GitLab
without coloring as a result, even though they are
fenced with a language label. If in a list, other items
will render as being in a code block too, even if not
meant to. This fixes all these issues, and cleans up
minor white space issues in install and integration docs
This is an initiative to ensure all documentation complies completely
with the Documentation Style Guide section "Documentation is the single
source of truth (SSOT)" according to this epic
https://gitlab.com/groups/gitlab-org/-/epics/1280.
In particular, the changes of this commit touch all files under
doc/install/. Most notably:
- install/redis.md:
Redirect to Redis section of install guide.
- install/pivotal/index.md:
Changed its content to reflect the current status, which is no
longer supported (since 2017!).
- install/google-protobuf.md:
Incorporated inside installation.md under the troubleshooting section.
- install/openshift_and_gitlab.md:
Clarified that this guide is no longer relevant. We might want to
redirect to the Chart docs in the future.
- install/structure.md:
Incorporated inside installation.md under its own section.
- install/kubernetes/index.md:
Redirected to https://docs.gitlab.com/charts
