This SDK isn't thread-safe (or even multi-process safe) because of OPTIONS cache

This SDK is crashing some of my build agents occasionally with this error:
[Errno 13] Permission denied: '/Users/USER_NAME/.azure-devops/python-sdk/cache/options.json'

Based on reading the code, it appears to be coming from here:
https://github.com/microsoft/azure-devops-python-api/blob/dev/azure-devops/azure/devops/_file_cache.py

This code doesn't appear to be at all thread, or even process, safe, as it just asserts handles to the file.
If it can't be made thread/process safe, some option to just not use the cache at all, and just fetch it directly when needed for the connection would work. As is now, I've had to implement a machine level mutex and lock all my calls to this API behind it, which is horribly inefficient, but I can't have my builds crashing with random IO errors.

从 azure-devops/azure/devops/_file_cache.py 开始，跟踪 SDK 连接期间如何打开和更新 options.json。尽可能重现并发访问失败，然后确定是否可以使缓存对线程和进程安全，或在禁用时绕过缓存。完成标准是：构建代理并发使用时不再产生所报告的权限错误，并且所选择的行为已有文档说明。
