Function mockLocalAPI

client/web/web_test.go:1450–1492

mockLocalAPI constructs a test localapi handler that can be used to simulate localapi responses without a functioning tailnet. self accepts a function that resolves to a self node status, so that tests may swap out the /localapi/v0/status response as desired.

// so that tests may swap out the /localapi/v0/status response
// as desired.
