Timeout, admin password and site id are set in many commands,
and we need to take care of synchronising the descriptions
and flags between them.
This change moves these standard options to cmd.go importing them
in the same manner CommonOpts imported by all commands already.
* explicitly ignore error from test connection close
* add client with timeout to places which used default http client
* move random port creation and waiting for server in separate function for reuse
* improve TestServer tests robustness
* move all server waiting code in tests to separate functions
* change chooseRandomUnusedPort to try to listen to port before return
* fix waitForHTTPSServerStart
* fresh vendor
* enforce vendor flag with env
* move tree to service package
* move controllers routing to rest.go, remove separate subrouters
* cleanup/formatting
* missing vendor packages
* move rss, img proxy, robots and getstarted to top-level routes
* simplify logger middleware usage
* randomize server test ports
* check for non-admin in admin tests
* lint: minor warns
* admin test to jwt admin
