Propagate DS_EXCLUDED_PATHS to dependency_scanning job,
and SAST_EXCLUDED_PATHS and SAST_BANDIT_EXCLUDED_PATHS to sast job.
This makes possible to excluded certains paths from SAST reports
and Dependency Scanning reports, respectively.

Improve indent for cache paths

Improve indent and remove empty lines

Part of https://gitlab.com/gitlab-org/gitlab-ce/issues/49520
(Covers helm charts; does not cover docker repos)

Reverts https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/26520
for Security/DAST.gitlab-ci.yml.

This reverts merge request !26954

Our templates are free to override the 'stages:'.
However, they should follow the convention to always include
'build', 'test', 'deploy' which are defaults when not defined.

Container Scanning, Dependency Scanning, License Management
and SAST parts of Auto DevOps now use the preexisting templates.

Auto DevOps and the DAST job template will now use a
shared job template instead of maintaining two copies
of the job. This also allows Auto DevOps to use custom
authentication with DAST.

This allows these templates to be used outside of Auto DevOps,
or easily excluded from Auto DevOps.

The security jobs in Auto DevOps differ slightly from the ones
that are already available as templates, they will be moved
next.

For some reason this value can be an empty string and we want to ensure
that we correctly fail the job before a deploy. This is particularly
problematic at the moment when coupled with
https://gitlab.com/gitlab-org/gitlab-ce/issues/54760 as the user has no
easy way to recover without destroying the cluster and starting over.

Revise logic of dependency caching, add cache key, make before script global.

Deploy boards now will check for app.gitlab.com/env and
app.gitlab.com/app

Update the template showing how to cache restored dependencies, add few variables, reduce before_script part, add and improve descriptions.

Tidies up CI templates to have better formatting.

* Removes redundant whitespace
* Removes redundant newlines

Update Dependency Scanning and add other templates

This commits add a job that is going to be triggered whenever someone
adds `[serverless deploy-functions]` text into their commit message.

This make it really simple to deploy functions in FaaS-only project.
