[ASTERIXDB-2148][FUN] Add init parameter for external UDF

- user model changes: no
- storage format changes: no
- interface changes: yes
  Added parameters to LibraryFunction in library.xsd.

Details:
By enabling init function in external UDF, a user can reuse the same UDF
implementation with different paramters. One example can be to reuse the
same Machine Learning algorithm with different model files by assigning
different file paths to the UDF parameter.
