Cristian Klein c32c9a510b fix(tiller): Avoid corrupting storage via a lock ... If two `helm upgrade`s are executed at the exact same time, then one of the invocations will fail with "already exists". If one `helm upgrade` is executed and a second one is started while the first is in `pending-upgrade`, then the second invocation will create a new release. Effectively, two helm invocations will simultaneously change the state of Kubernetes resources -- which is scary -- then two releases will be in `deployed` state -- which can cause other issues. This commit fixes the corrupted storage problem, by introducting a poor person's lock. If the last release is in a pending state, then helm will abort. If the last release is in a pending state, due to a previously killed helm, then the user is expected to do `helm rollback`. This is a port to Helm v2 of #7322.
