* Move some more atomic values under Channels The following fields were moved: ``` asymmetricSigningKey atomic.Value clientConfig atomic.Value clientConfigHash atomic.Value limitedClientConfig atomic.Value ``` And also moved the initialization order from NewServer to Channels.Start to better reflect the order of things. Removed AsymmetricSigningKey from ConfigService as it was no longer used. Removed calling regenerateClientConfig during startup explicitly because it was anyways called from ensureAsymmetricSigningKey. https://community-daily.mattermost.com/boards/workspace/zyoahc9uapdn3xdptac6jb69ic/285b80a3-257d-41f6-8cf4-ed80ca9d92e5/495cdb4d-c13a-4992-8eb9-80cfee2819a4?c=87df1e15-588e-49ff-8bd1-ffa9651b8c82 ```release-note NONE ``` * Fix lint error ```release-note NONE ```
