[SO-ETSI-NFVO] Add SO DB and NFVO DB Credentials to NFVO NS LCM Pod for DB Communication

[SO-ETSI-NFVO] Add SO DB and NFVO DB Credentials to NFVO NS LCM Pod for DB Communication

All of the credentials added have been accessed using the common secrets template.
In order to avoid hardcoding passwords etc.

I have added 2 jdbcUrl's for accessing the NFVO DB and the CamundaBPMN DB. These will be needed for code going into the SO codebase.

This change should not have an effect on any other charts, as properties have only been added to ETSI NFVO Charts.
