#38 Resetting PcpMmvWriter does not clear all objects related to metrics ( https://github.com/performancecopilot/parfait/issues/38 )

Calling io.pcp.parfait.dxm.BasePcpWriter#reset clears metricData but there are several references held on to PcpMetricInfo s, InstanceDomain s, PcpString s and PcpValueInfo s ( PcpValueInfo s are cleared in metricData map but there is a reference held in the perMetricByteBuffers map).

Maps/arrays/stores are as follows: io.pcp.parfait.dxm.BasePcpWriter#metricInfoStore io.pcp.parfait.dxm.BasePcpWriter#instanceDomainStore io.pcp.parfait.dxm.PcpMmvWriter#stringInfo io.pcp.parfait.dxm.BasePcpWriter#perMetricByteBuffers These data structures should also be cleared out when #reset is called. I'm more just making a note of this at the moment. I noticed this when working on MMV v2 support but haven't tackled this object leak as part of that issue. The patch set is already fairly large.
