Improve smartness of `Tower.Event.similarity_id` when minor dynamic values part of Exception reason string

[grzuy]

Examples:

• When Exception error message/reason contain an inspected PID
• (DBConnection.ConnectionError) connection not available and request was dropped from queue after 1620ms. This means requests are coming in and your connection pool cannot serve them fast enough.

Original implementation: #61.
