Allow commit.retry.num-retries specified in extra_properties

[jinyangli34]

Description

After 470, commit.retry.num-retries became a supported trino property with key max_commit_retry
It no longer allows specifying commit.retry.num-retries in extra_properties and fails on verifyExtraProperties check.

Fixing it by checking if property is specified in extra_properties.

I don't think we want to allow setting commit.retry.num-retries via extra_properties anymore.

that causes issue when upgrading the cluster. user cannot have a query working for both older/newer versions.
