Enhance gokv library in order to allow full persistency of Redis DB #1
Description
The opi-evpn-br uses the https://github.com/philippgille/gokv/tree/master library in order to give the flexibiity to the user to choose its own DB backend.
The main database that is used for the opi-evpn-br project is Redis. In order to make Redis to create a snapshot of the DB everytime that we do a write operation we need to execute the BGSAVE redis command. The gokv currently doesn't support this kind of command which means that Redis is not persistent and this can lead to loss of data. We need to enhace the gokv library in order to achieve persistency by executing BGSAVE after each write operation in Redis if the user chooses to have persistent data versus in memmory data.
