optimize: A new subcommand that either gets or drops file content as needed to work toward meeting the configured numcopies setting.

Browse source 
This is currently rather simplistic, though still useful.
In the future, it could become smarter about what content is stored where,
etc.

Once you have multiple repositories, and have perhaps configured numcopies,
any given file can have many more copies than is needed, or perhaps fewer
than you would like. Fsck can detect the latter problem, but there's another
command that can help deal with both problems.
The optimize subcommand either gets or drops file content, as needed,
to work toward meeting the configured numcopies setting.
# git annex optimize
get my_cool_big_file (from laptop...) ok
drop other_file ok
# git annex optimize --numcopies=2
get other_file ok
