Improvements

Support for Open Session in View (OSIV)

Datasource Micrometer now better supports Open Session in View (OSIV) by shortening the observation scope for JDBC connections. (#82)

Previously, when OSIV was enabled, the observation scope for a JDBC Connection could remain open due to delayed connection closing.
With this change, the observation scope for the connection is shortened so that long-lived connections (caused by OSIV) do not cause observations to extend beyond appropriate boundaries.
