Ring member refresh log improvements

[taylanisikdemir]

What changed?
The refreshed ring members log is useful for troubleshooting membership change related issues. However it lacks a few things:

• count of members as separate log tag
• sorted member list to easily export/diff logs
• the service name that the ring belongs to.

How did you test it?
CI checks
