Add TLS ServerName as CLI option for Cadence Cassandra Tool

[sonpham96]

What changed?

• Add ServerName as CLI option for cadence-cassandra-tool
• Pass the ServerName to the cql client TLS config

Why?
Fix #5010.

How did you test it?
I built the cadence-server Docker image then execute the following command:

docker run --rm ubercadence/server:master --tls -u <user> --pw <password> --ep <endpoint> -p 9042 --tls-server-name <endpoint> -k cadence update-schema -d /etc/cadence/schema/cassandra/cadence/versioned

The error did not appear and the command finished successfully.

Potential risks
N/A

Formatted the code with make fmt. Hope it will fix the lint errors. However, it looks like the build is blocked. How do I trigger it?
