Updated hapi instrumentation to support the recently released v6.9.
Fixed a bug where an invalid package.json could cause the agent to crash while it recursed through
node_modulesgathering version details.
Previously when the agent failed to parse SQL it would create a metric stating the database type, query type, and query table were all unknown. This has been changed to keep track of database type and create an appropriate
otheroperation metric like other agents.
