docs: Reverses and cleans an instance path.
  <p>
  In fact, this method creates a string from an instance path
  that is reverted (the root becomes the leaf and the lead the root).
  Then, it cleans it with {@link #cleanInstancePath(String)}.
  This can be used to create proper (and readable) IDs to use in scripts (e.g. to name
  a Docker container - see #506).

  @param instancePath a non-null instance path
  @return a non-null string
