Changes to search_api_opensolr.opensolrconfig.yml configuration file

A new key was added to the opensolr global configuration file.

The contents of the configuration file were changed as follows:

Previously

opensolr_credentials:
  email: ''
  api_key: ''

Currently

opensolr_credentials:
  email: ''
  api_key: ''
  api_key_raw: ''

Since the Key module is now optional, the api_key key will continue to hold the key that stores the actual opensolr API key, and the newly added api_key_raw key will hold the raw opensolr API key when not using the optional module. When one is set, the other one will be empty.
