Remove the method cancelOperation

Remove this because maps-search's lro doesn't support cancelation.
For future lro that support cancelation, we should use the `createHttpPoller`
like the one in the [ai-language-text](https://github.com/Azure/azure-sdk-for-js/blob/cb198d21c4f377e9d2d57744523b8eb3f45a2fb6/sdk/cognitivelanguage/ai-language-text/src/textAnalysisClient.ts#L686)
