Migrated configureclouds redirect from groovy to jelly

[StefanSpieker]

Migrated configureclouds redirect from groovy to jelly. If you think, deleting the redirect is even better, I'm also fine doing this.

Testing done

started jenkins in debug and verified that redirect is working from configureClouds to /manage/cloud

I also used a curl command curl -vL to verify that it is working:

Submitter checklist

• The Jira issue, if it exists, is well-described.
• The changelog entries and upgrade guidelines are appropriate for the audience affected by the change (users or developers, depending on the change) and are in the imperative mood (see examples). Fill in the Proposed upgrade guidelines section only if there are breaking changes or changes that may require extra steps from users during upgrade.
• There is automated testing or an explanation as to why this change has no tests.
• New public classes, fields, and methods are annotated with @Restricted or have @since TODO Javadocs, as appropriate.
• New deprecations are annotated with @Deprecated(since = "TODO") or @Deprecated(forRemoval = true, since = "TODO"), if applicable.
• New or substantially changed JavaScript is not defined inline and does not call eval to ease future introduction of Content Security Policy (CSP) directives (see documentation).
• For dependency updates, there are links to external changelogs and, if possible, full differentials.
• For new APIs and extension points, there is a link to at least one consumer.

Desired reviewers

@mention

Before the changes are marked as ready-for-merge:

Maintainer checklist

• There are at least two (2) approvals for the pull request and no outstanding requests for change.
• Conversations in the pull request are over, or it is explicit that a reviewer is not blocking the change.
• Changelog entries in the pull request title and/or Proposed changelog entries are accurate, human-readable, and in the imperative mood.
• Proper changelog labels are set so that the changelog can be generated automatically.
• If the change needs additional upgrade steps from users, the upgrade-guide-needed label is set and there is a Proposed upgrade guidelines section in the pull request title (see example).
• If it would make sense to backport the change to LTS, a Jira issue must exist, be a Bug or Improvement, and be labeled as lts-candidate to be considered (see query).

It's a redirect since #7658 in 2.403, probably safe to delete at this point. Thoughts @Vlatombe ?

I also used a curl command curl -vL to verify that it is working:

Due to .. use here instead of rootURL as before (and the insanity coming from #6126), the result is a little awkward with /manage/configureClouds which was the most likely URL though which the old configuration was accessed.

Suggested change

	<st:redirect url="../manage/cloud/" />
	<st:redirect url="../cloud/" />

is probably a better approach, as it should neither add nor remove /manage/ (untested).

I guess it shouldn't matter anymore.
