Relative

# Problem

There is a different behavior of various plugins whether their name is absolute or relative, including:

1. mounting the same file somewhere else does not work
2. importing somewhere else (other than from where it was exported) does not work (See here)

# Constraints

- at least the dump plugin must be able to handle its old files

# Assumptions

- it still will be easy to support a workflow that exports/imports everything
- mounting across namespaces (user/system) does not make sense

# Considered Alternatives

- allow relative/absolute plugins and mark them what they are, tools (e.g. import/export) use this knowledge and react accordingly. This would still not solve problem 1.)

# Decision

Key names shall be relative to parent key name.

# Rationale

Provides a better import/export/remount and also a more uniform experience between different plugins.

# Implications

All plugins that had absolute paths were adapted, see #51.
