Revise GitLab Geo documentation

Closes #3365 and #3400

See merge request gitlab-org/gitlab-ee!2858

This ensures that if a pipeline is present for the last commit on a
project's homepage we only run 1 query to get the builds, instead of
running 2 queries.

See https://gitlab.com/gitlab-org/gitlab-ce/issues/36878#note_40073339
for more information.

This adds Project#latest_successful_pipeline_for and
Project#latest_successful_pipeline_for_default_branch. The 2nd method
memoizes the result (taking nil values into account) to ensure the
underlying query isn't executed multiple times when viewing a project's
homepage.

See https://gitlab.com/gitlab-org/gitlab-ce/issues/36878#note_40073607
for more information.

Updated Doc: Omitting AWS access key and ID key=>value pairs when using AWS IAM profiles

See merge request gitlab-org/gitlab-ee!2892

Closes https://gitlab.com/gitlab-org/gitlab-ce/issues/37875

Fixes include:
- GitLab 10.0 depends on the tracking database (because of the removal
  of System Hooks in gitlab-org/gitlab-ee!2644), therefore the docs
  should clearly state how to set up and update the Geo tracking
  database.

- To initiate synchronization it's no longer needed to push first.
  Geo will automatically pick up new projects, and it's no longer needed
  to push to the repo before GitLab Geo will start syncing.

- Small changes to improve consistency through the whole docs.

Closes gitlab-org/gitlab-ee#3365 and gitlab-org/gitlab-ee#3400
