How to remove node-taint via apiclient?

[makarov-roman]

Hi,

I have the following use case:

1. there is a taint by default on our nodes
2. bootstrap container fetches pullsecret
3. if it succeded remove the taint

the trouble is with the step 3, I can't find how to remove it from the config. Here are some examples of what I've tried:

apiclient set --json '{"kubernetes": {"node-taints": {"pullsecrets-not-ready": []}}}'
Failed to change settings: Failed PATCH request to '/settings?tx=apiclient-set-aFXHfCsm713hVmCu': Status 400 when PATCHing /settings?tx=apiclient-set-aFXHfCsm713hVmCu: Json deserialize error: empty taint value at line 1 column 57

apiclient set --json '{"kubernetes": {"node-taints": {}}}'
Failed to change settings: Failed POST request to '/tx/commit_and_apply?tx=apiclient-set-AB7MA1Cd92vVA8JA': Status 422 when POSTing /tx/commit_and_apply?tx=apiclient-set-AB7MA1Cd92vVA8JA: Tried to commit with no pending changes

Thanks!
