SOLR-16632: Add core name to periodic delete related log messages

[bszabo97]

https://issues.apache.org/jira/browse/SOLR-16632

Description

When expired documents are deleted periodically from the index we have a log message about the start and the end of this process.

In cases where we have multiple collections with TTL enabled it can be misleading that these messages do not contain the name of the actual collection/core on which the periodic delete is executed. The name of the core can be easily added to the log message.

Solution

I have added core.getName() as a parameter to the above mentioned log lines.

Tests

I have manually tested that the core name appears in the log messages after my modification.
