P4 with Broker fails on TeamCity Server

Greetings!

The perforce plugin is trying to get `p4 info` on the server before logging in. Since we use a broker for authentication, it does not return a server address until after you are logged in, so it is failing with (changing the info I cannot share to ****):

Couldn't find server info in 'p4 info' output: User name: teamcity

The agent works fine; it is logged in. Because we share a server with other teams, we cannot access the server, only the agent. We have it set to checkout on the agent only, but it seems that even then the server tries to collect changes itself before moving on to starting the build on the agent. It has worked a couple of times, so it might be logging in sometimes.

1. In what cases does it login without trying to do a `p4 info` command first? We could use that to workaround if it's possible. 

2. Alternatively, is there a way to collect changes on the agent instead of on the server?

Basically, is our only option to manually sync p4 with a script we run on the agent? 

Thanks!
