add $ENVIRONMENT to PCG_REDIS_NAME in secret repository

[jinhan]

This issue is about your secret repository's local sh file.

When the major bump of local cluster, there is a discrepancy between Redis instance's authorized network name and current network name. Subsequently, the pcg cache is not working.

It's because PCG_REDIS_NAME already exists when creating Redis instance while launching a new cluster, so the authorized network name is not updated and remains the previous one.

To prevent this, I think we need to add $ENVIRONMENT to PCG_REDIS_NAME, which allows to create a new Redis instance with a new authorized network name.

export PCG_REDIS_NAME=pcg-cache-$ENVIRONMENT
