[Showstopper] Cannot use continuation token in API 7.0 and above (thus limiting number of results)

Hi, in earlier versions of the API (until 6.0.0b4), when making a request on some items (e.g. WorkItems, Test Suites, ...), you had a response object with a value and a continuation_token that you could use to make a new request and continue parsing.

For example, here is the prototype of such function:

    def get_test_suites_for_plan(self, project, plan_id, expand=None, continuation_token=None, as_tree_view=None):
        """GetTestSuitesForPlan.
        [Preview API] Get test suites for plan.
        :param str project: Project ID or project name
        :param int plan_id: ID of the test plan for which suites are requested.
        :param str expand: Include the children suites and testers details.
        :param str continuation_token: If the list of suites returned is not complete, a continuation token to query next batch of suites is included in the response header as "x-ms-continuationtoken". Omit this parameter to get the first batch of test suites.
        :param bool as_tree_view: If the suites returned should be in a tree structure.
        :rtype: :class:`<GetTestSuitesForPlanResponseValue>`

So you could do something like:

resp = client.get_test_suites_for_plan(project, my_plan_id)
suites = resp.value
while resp.continuation_token:
    resp = client.get_test_suites_for_plan(project, my_plan_id)
    suites += resp.value

With more recent versions (in particular 7.0), you now get a list returned (but with the limit of size imposed by the API).

For example, a version of similar function would be:

    def get_test_suites_for_plan(self, project, plan_id, expand=None, continuation_token=None, as_tree_view=None):
        """GetTestSuitesForPlan.
        [Preview API] Get test suites for plan.
        :param str project: Project ID or project name
        :param int plan_id: ID of the test plan for which suites are requested.
        :param str expand: Include the children suites and testers details.
        :param str continuation_token: If the list of suites returned is not complete, a continuation token to query next batch of suites is included in the response header as "x-ms-continuationtoken". Omit this parameter to get the first batch of test suites.
        :param bool as_tree_view: If the suites returned should be in a tree structure.
        :rtype: :class:`<[TestSuite]> <azure.devops.v6_0.test_plan.models.[TestSuite]>`
        """

How to retrieve the continuation token to continue parsing the other results?

首先追蹤產生的 get_test_suites_for_plan 方法，並比較其對 v6 和 v7 回應的處理方式。檢查該方法傳回清單時如何表示 x-ms-continuationtoken 標頭。完成標準是確認受影響 endpoints 存在可用的 continuation-token 路徑，或記錄目前 API 無法公開該路徑的原因。
