refactor: log topology and increase reconnect interval

[karenc-bq]

Summary

• Log topology and increase reader reconnect interval

Description

• The JDBC Wrapper attempts to reconnect to a reader every 1 millisecond if the previous attempt fails, increasing the sleep timeout to avoid spamming the reconnect
• Moved the location of a log message so explicit read status doesn't get logged excessively for every execute method
• Log topology when initializing host list provider
• Changed the log level for failover errors to a more appropriate level.
