Caddy: why not decrease the size of release assets?

[yu-chenxi]

Currently, all release assets have debug info and they are uncompressed. I think it is very necessary to decrease the size of them. Here are some ways:

1. the original
   your can see, the debug info of asset is not stripped, which size is 30M.

2. strip the debug info
   Decreased by 7M, about 23% of the original size. And it is safe to strip the debug info when build . you can use go build -ldflags="-s -w" to achieve this goal. Just add -ldflags="-s -w" to azure pipeline file.
   see also: https://golang.org/cmd/link/ to know the meaning of arguments above.

3. compress it
   Only 6M, about 20% of the original size.

4. or use UPX to pack it
   A standalone executable file only 7.2M, so fantastic!

Currently the release binaries aren't produced by the azure-pipelines.yml flow. I think Matt hand-rolls them for now while v2 is still in beta.

For the record, I think we need to keep debug info, so that panics and other stack traces contain useful information.

Edit: @Mohammed90 has pointed out to me that stripping debug symbols still preserves stack traces, so that's good.
