removed configsync dependency

[henderiw]

Removed the dependency to configsync namespace, but we need to see if the namespace is to be set.

[henderiw]

So this PR adds 2 changes to make it independent on configsync.

1. the syncApp should be changed from configsync to tobeinstalledonremotecluster
2. the remoteNamespace can be set. For Configsync this has to eb set.

@henderiw If I understand correctly I still have to create the secret in the management cluster right? Only then Nephio-Controller will act on it. In this case is it possible to add a possibility to populate the secret in the multiple clusters?

right now there is a clusterName we lookup because we need to find the credentials of the remote cluster. I also believe it is bad practice to reuse a secret in multiple places, because a break means you have to update all of them.
So right now it is 1:1

But in skupper that's how a link between two sites is created, a secret is shared between clusters (same namespaces).

[henderiw]

@arora-sagar I added logic to add the secret to a multiple clusters.
