Stored certificates and keys in the repository

[pavel-jares-bcm]

The repository contains some keys and certificate in folder /keystore. Even they are only for testing, we should consider:

• not storing keys in plain text
• don't providing passwords to the keystores (the password could be stored in GA)
• clean up of the folder to omit duplicity files in there
• posibility to generate keys before test (using automated tests) and avoid sharing these keys between users
