Redis-master renamed to something uitsmijter related

Hello,

a request from the EE version is that the Redis database should have a unique name. We recommend to install Uitsmijter in a separate namespace, but a request from the customer is that Uitsmijter coexists with an application that already has a Redis database.

We decide to open-source this change request and integrate a unique name into the main branch.
We also decide that now is the best time before we release an official V1, as the change will affect existing installations.

When a new version is rolled out, the services must be deleted as the names will also change.

We will also introduce a new global setting for the location of tenants and clients. By default it will still be .allNamespaces, but you can narrow it down to a specific location.

It will be available with the helm configuration and will be documented shortly.
