tests: optimize test-copytrace-heuristics.t
test-copytrace-heuristics.t tests the heuristics algorithm of copytracing. The
test has a pattern of making a server repo first and then cloning into a local
repo for each test to have public and draft commits. This is done because if we
have all draft commits and we have very less commits, heuristics will fallback
to full copytracing as that will be fast.
To avoid creating the server repo, we set the commit limit to -1 so that
everytime we perform the heuristics algorithm even when having full drafts and
tweak the config setting when we need to test the ability to fallback to full
copytracing.
This optimizes this test by 3 seconds.

'''http authentication with factotum
This extension allows the factotum(4) facility on Plan 9 from Bell Labs
platforms to provide authentication information for HTTP access. Configuration
entries specified in the auth section as well as authentication information
provided in the repository URL are fully supported. If no prefix is specified,
a value of "*" will be assumed.
By default, keys are specified as::
proto=pass service=hg prefix=<prefix> user=<username> !password=<password>
If the factotum extension is unable to read the required key, one will be
requested interactively.
A configuration section is available to customize runtime behavior. By
default, these entries are::
[factotum]
executable = /bin/auth/factotum
mountpoint = /mnt/factotum
service = hg
The executable entry defines the full path to the factotum binary. The
mountpoint entry defines the path to the factotum file service. Lastly, the
service entry controls the service name used when reading keys.
