* Rename 'vendor/src' -> 'vendor' * Ignore vendor/ instead of vendor/src/ for lint * Rename 'cmd/client' -> 'cmd/ocic' to make it 'go install'able * Rename 'cmd/server' -> 'cmd/ocid' to make it 'go install'able * Update Makefile to build and install from GOPATH * Update tests to locate ocid/ocic in GOPATH/bin * Search for binaries in GOPATH/bin instead of PATH * Install tools using `go get -u`, so they are updated on each run Signed-off-by: Jonathan Yu <jawnsy@redhat.com>
