Resuming nodes

[alexec]

In #1893 the ability to resume nodes based on a "node field selector" was introduced. This included a test named TestNodeSuspendResume.

This test was sporadically failing on master, so in #2543 I increased the timeout from 10s to 20s. This actually made the test reliably fail, the exact opposite of what I expected.

This suggests that the test is probably valid - therefore there might be an underlying bug.

This is the error:

collins8@intuitdepe1a95 argo (⎈ |k3s-default:argo) (longer-timeout)]$ argo resume node-suspend --node-field-selector inputs.parameters.tag.value=suspend1-tag1
2020/03/30 13:29:40 Failed to resume node-suspend: rpc error: code = Unknown desc = No nodes matching nodeFieldSelector: inputs.parameters.tag.value=suspend1-tag1

@mark9white I've created a bug and would love it if you could take a look.
