AbstractDaemonTest: Don't delete common server path too early

Chaining the TemporaryFolder with the custom TestRule results in the
directory for the common server being deleted after the first test
method, even though it might still be needed. This means a @UseLocalDisk
class cannot have more than one method, or things break, including but
not limited to the NRT reopen threads throwing exceptions due to the
index files disappearing out from under them. We just got lucky that
none of our local disk tests were actually affected by this.

To make this work, we can't tie the lifetime of the TemporaryFolder to a
single AbstractDaemonTest method invocation. Instead, create the tempdir
within GerritServer#initAndStart, and allow callers to get it back out.
We have to be a bit more careful about managing the lifetime of the
tempdir since some GerritServers, particularly in StandaloneSiteTest,
have a shorter lifetime than their tempdirs. Fortunately, TempFileUtil
make this relatively easy.

As a nice side effect, we can get rid of the hack of passing the tempdir
in via a Gerrit config option.
