Clones this object. This is useful because multiple builder instances may
use a similar set of parameters. However, single instances of parameter
objects must not assigned to multiple builders. Therefore, cloning a
parameters object provides a solution for this use case. This method
creates a new parameters object with the same content as this one. The
internal map storing the parameter values is cloned, too, also collection
structures contained in this map. However, no a full deep clone operation
is performed. Objects like a
ConfigurationInterpolator or
Lookups are shared between this and the newly created instance.
