Use escape character over double quoting in generated CSV

[ebeahan]

Summary

Adjust the params in the csv.writer() object in the CSV generator to use escape \ as an escape characters for double quotes within an already quoted field. Default behavior generates field values with double double-quotes.

Behavior was noted while working on #966.

Example

Current:

2.0.0-dev,true,base,labels,object,core,,"{""application"": ""foo-bar"", ""env"": ""production""}",Custom key/value pairs.

PR:

2.0.0-dev,true,base,labels,object,core,,"{\"application\": \"foo-bar\", \"env\": \"production\"}",Custom key/value pairs.

Side Effect

One small, side-effect change is example values themselves containing \ as part of their string values will now be quoted:

Current:

2.0.0-dev,true,dll,dll.path,keyword,extended,,C:\Windows\System32\kernel32.dll,Full file path of the library.

PR:

2.0.0-dev,true,dll,dll.path,keyword,extended,,"C:\Windows\System32\kernel32.dll",Full file path of the library.

Adding backslash escaping into CSV breaks default importing into a spreadsheet app, so I won't move forward pursuing this change for now.
