'upstream' trigger can now be used as a server command also

Browse source 
i.e., a client fetch will invoke the push, (subject to 'nice' setting),
but you can also force a fetch regardless of last fetch time by running
this command directly on the server:

    gitolite ../triggers/upstream fetch <reponame>

Also, use FETCH_HEAD instead of own sentinel file (idea courtesy Luke Lu)

# manage local, gitolite-controlled, copies of read-only upstream repos.
# Every time a client fetches such a repo, an upstream fetch happens, then the
# client fetch is completed. Optionally, you can be "nice" and impose a
# minimum delay between 2 fetches.
# See bottom of file for instructions and notes.

# To install, add 'upstream' to the PRE_GIT trigger list in the rc file.
#
# Example setup to manage your own copy of the git repository:
# repo git
# R = @all
# RW+ my-company/ = @developers
# option upstream.url = git://git.kernel.org/pub/scm/git/git.git
# option upstream.nice = 120 # (optional) minimum 2 hours between fetches
# FEATURES:
# * invokes upstream fetch on each local fetch
# (unless the optional 'nice' setting is enabled)
# * can force a fetch (ignoring 'nice' value) from server CLI
# Notes:
# 1. we don't use a remote; due to refspec being +refs/*:refs/* we don't need one
# 2. please restrict local pushes, if any, to a namespace that the upstream won't use
# 3. if the upstream URL changes, change the conf file accordingly and push the admin repo
# INSTRUCTIONS:
#
# * add 'upstream' to the PRE_GIT trigger list in the rc file.
# * add option lines to conf file. For example:
#
# repo git
# R = @all
# RW+ my-company/ = @developers
#
# option upstream.url = git://git.kernel.org/pub/scm/git/git.git
# option upstream.nice = 120
#
# * to force a fetch on the server shell (or via cron), run this command:
# gitolite ../triggers/upstream fetch reponame
# ADDITIONAL NOTES:
# * restrict local pushes to a namespace that the upstream won't use
# (otherwise the next fetch will wipe them out)
# * if the upstream URL changes, just change the conf and push admin repo
# * the 'nice' setting is in minutes and is optional; it is the minimum
# elapsed time between 2 upstream fetches.
