Bug 19465: Add --elasticsearch-server option to koha-create

This patch adds the --elasticsearch-server option switch to koha-create.
It allows choosing a different Elasticsearch configuration. It defaults
to the current 'localhost:9200' value.

To test:
- Apply this patches
- Run:
  $ reset_all
  $ man koha-create
=> SUCCESS: The man page shows correct information about the added
option switch
- Run:
  $ sudo koha-create --create-db test
=> SUCCESS: /etc/koha/sites/test/koha-conf.xml contains the default
   value (i.e. the current behaviour is kept)
- Run:
  $ sudo koha-create --create-db --elasticsearch-server tomas:1234 test2
=> SUCCESS: /etc/koha/sites/test2/koha-conf.xml contains the passed
   value in the <elasticsearch><server> section.
- Sign off :-D
