Gabor Somogyi 28ced387b9 [SPARK-26772][YARN] Delete ServiceCredentialProvider and make HadoopDelegationTokenProvider a developer API ... ## What changes were proposed in this pull request? `HadoopDelegationTokenProvider` has basically the same functionality just like `ServiceCredentialProvider` so the interfaces can be merged. `YARNHadoopDelegationTokenManager` now loads `ServiceCredentialProvider`s in one step. The drawback of this if one provider fails all others are not loaded. `HadoopDelegationTokenManager` loads `HadoopDelegationTokenProvider`s independently so it provides more robust behaviour. In this PR I've I've made the following changes: * Deleted `YARNHadoopDelegationTokenManager` and `ServiceCredentialProvider` * Made `HadoopDelegationTokenProvider` a `DeveloperApi` ## How was this patch tested? Existing unit tests. Closes #23686 from gaborgsomogyi/SPARK-26772.
