v5.2.0 logs tab added

Problem

Sometimes when schema registration fails, its hard to trace why.
You need to either check schema-registry logs, or you need to debug endpoint response output on client side
This adds Logs UI which shows all logs that schema-registry does via regular logger.error() functions, just uses redis as a temporary storage

Changes

• add logs tab (reads from redis)
• add info component
• add winston-redis-stream for temporary storage for logs
