How to bypass the token insertion(from teamcity-server.log to web page) step in the upgrade workflow?

Hello,

We have built an automation to upgrade the TeamCity instance using our in-house tool.

One of the interesting steps is, copying the token generated in "teamcity-server.log" to TeamCity web page.

Is there any API or HTML endpoint which can be used to automatically bypass this manual step?

For eg, grepping the token from log and calling curl command to this endpoint.
