Diagnostic Dump excludes some logfiles

Repro steps.

• Create an Azure WebApp and add the New Relic .NET Agent extension.
• NewRelic logfiles are written to C:\home\LogFiles\NewRelic and can be browsed, downloaded and edited via the Kudu Debug Console.
• Browse to C:\home\LogFiles\NewRelic in the Kudu Debug Console and note which files are present.
• Generate a Kudu Diagnostic Dump.
• Note that two files are missing - one of the NewRelic.Profiler.*.log files and the newrelic_agent_xxx.log file.
• Stop the WebApp
• Generate a new Kudu Diagnostic Dump
• Note that the two missing files are now included.

NewRelic uses Serilog for writing the log files, which retains an open handle to the file, but opens the file for shared access. There would appear to be some conflict with the Diagnostic Dump tool where it's trying to gain an exclusive lock on the files it adds to the output zip file.
