Rebecca Stambler b12e6172dc internal/lsp/cache: don't delete metadata until it's reloaded ... Retrying CL 271477, this time with parts of CL 322650 incorporated. This CL moves to a model where we don't automatically delete invalidated metadata, but rather preserve it and mark it invalid. This way, we can continue to use invalid metadata for all features even if there is an issue with the user's workspace. To keep track of the metadata's validity, we add an invalid flag to track the status of the metadata. We still reload at the same rate--the next CL changes the way we reload data. We also add a configuration to opt-in (currently, this is off by default). In some cases, like switches between GOPATH and module modes, and when a file is deleted, the metadata *must* be deleted outright. Also, handle an empty GOMODCACHE in the directory filters (from a previous CL).
