       This plugin can be used to perform rename operations on keys passing by. This might be
       useful if a backend does not provide keys in the required format. If keys are renamed,
       their original name is stored in the origname MetaKey.

   CUT
   OPERATION
       The cut operation can be used to strip parts of a keys name. The cut operation is able to
       cut anything starting after the path of the parent key. A renamed key may even replace the
       parent key. For example consider a KeySet with the parent key user/config. If the KeySet
       contained a key with the name user/config/with/long/path/key1, the cut operation would be
       able to strip the following key name parts:

       • with

       • with/long

       • with/long/path

       • with/long/path/key1

   CONFIGURATION
       The cut operation takes as its only configuration parameter the key name part to strip.
       This configuration can be supplied in two different ways. First, the global configuration
       key cut can be used. Second, keys to be stripped can be tagged with the MetaKey
       rename/cut. If both options are given, the MetaKey takes precedence. For example, consider
       the following setup:

                                   `config/cut` = will/be
                                   parent key = user/config

                                   user/config/will/be/stripped/key1                       <- meta rename/cut = will/be/stripped
                                   user/config/will/be/stripped/key2                       <- meta rename/cut = will/be/stripped
                                   user/config/will/be/stripped/key3
                                   user/config/will/not/be/stripped/key4

       The result of the cut operation would be the following KeySet:

                                   user/config/key1
                                   user/config/key2
                                   user/config/stripped/key3
                                   user/config/will/not/be/stripped/key4

       The cut operation is agnostic to a single trailing slash in the configuration. This means
       that it makes no difference whether cut = will/be/stripped or cut = will/be/stripped/.
       However, the cut operation refuses cut paths with leading slash. This is to clarify that
       key name parts can only be stripped after the parent key path.

       If an invalid configuration is given or the cut operation would cause a parent key
       duplicate, the affected keys are simply skipped and not renamed.

   PLANNED OPERATIONS
       Additional rename operations are planned for future versions of the rename plugin:

       • trim: remove spaces in the name (that are not part of parentKey!)

       • case: upper/lowercase the name (that are not part of parentKey!)
