Properties files directories in the channels

The following points should be updated in the properties files:

• Directories of the properties file and other files references. You can look for the #SUSTITUIR# word to find the references to update.
• Configuring the certificate manager.
• Configuring certificates registered in the system.
• Revising the services of endpoints because by default the endpoints included are the ones provided by the AEAT for testing. The AEAT endpoints for production are commented in properties files.
