This change adds support for goimports as a code action that can be run
on save. However, there do appear to be issues with the propagation of
the context.Only field of the CodeActionParams, so we treat every
codeAction as an organizeImports action - this should be fixed in the
next vscode-languageclient release
(https://github.com/Microsoft/vscode-languageserver-node/issues/442).
