type ContainerExecUncachedMetadata added in v0.8.8 

type ContainerExecUncachedMetadata struct {
	ParentClientIDs []string `json:"parentClientIDs,omitempty"`
	ServerID        string   `json:"serverID,omitempty"`
	ProgSockPath    string   `json:"progSockPath,omitempty"`
}

Metadata passed to an exec that doesn't count towards the cache key. This should be used with great caution; only for metadata that is safe to be de-duplicated across execs.

Currently, this uses the FTPProxy LLB option to pass without becoming part of the cache key. This is a hack that, while ugly to look at, is simple and robust. Alternatives would be to use secrets or sockets, but they are more complicated, or to create a custom buildkit worker/executor, which is MUCH more complicated.

If a need to add ftp proxy support arises, then we can just also embed the "real" ftp proxy setting in here too and have the shim handle leaving only that set in the actual env var.
