Merge from OSDU-delfi: !205409 replace RedisCache with VmCache (loadingCache)
- Change redis cache to VmCache
- Remove all redis cache deployment and config files
- Set cache expiration time to 5 minutes, maximum cache size to 1000
REDIS cache is exposed outside of the Kubernetes boundary, which provides a potential security risk. It also has a slight performance penalty since each call requires a network request. There may also be some configuration complications with setup since we have to know where REDIS is and align with it. Therefore we want to use a local in-service memory cache instead of a standalone cache process.
