reap-ec2-instances: initial commit

This just goes through and kills any instances over a given age
Examples:
 ./reap-ec2-instances --region us-east-1 --max-age 1d
 ./reap-ec2-instances --max-age=3600

better handle cleaning up of instances in failed publish-build-ebs

publish-build-ebs was "leaking instances" when one of the builds failed.

The primary problem was that the previous code expected that
a subshell's signal handlers were inherited from their parent. That is
simply not true.

The changes here primarily address that, but also address general
signal handing of the SIGINT and SIGTERM.

Note, that in publish-build-ebs, we still wait for each region to finish
serially. That means that if we're publishing in the following order:
 us-east-1
 us-west-1
 ap-northeast-1
 sa-east-1

and ap-northeast-1 fails immediately, we'll continue on blissfully until
both us-east-1 and us-west-1 finish. At that point, it will recognize
that ap-northeast-1 has failed, and kill any jobs (possibly sa-east-1)
that are still running.

The potential fix for that would be to add a signal handler for SIGCHLD
and then somehow check its return code and trigger cleanup code then.

run-instance-and-wait: make tag creation silent

'xc2 tag' was writing output to stdout. This program should not have
anything written to stdout other than instance-id and host.

That caused the user of it (publish-build-ebs) to read the string 'TAG'
as the instance id.

change failure of 'xc2 tag create' to warning [temporary]

The version of boto used on nectarine was not new enough to
have support for 'create_tag', and thus this was killing builds.

Example failure from maverick-server 20120204.

Traceback (most recent call last):
  File "/home/vmbuilder/ec2-daily/xc2/xc2-helper-tag", line 126, in <module>
    main()
  File "/home/vmbuilder/ec2-daily/xc2/xc2-helper-tag", line 118, in main
    ret = tag_create(conn, args[1:], options.tags)
  File "/home/vmbuilder/ec2-daily/xc2/xc2-helper-tag", line 41, in tag_create
    response = conn.create_tags(resources, tagdict)

clean up two issues in detach_vol of publishing ec2 ebs volumes.

publish-image: do not match ebs images when looking for instance-store

when looking for an existing image, we were searching like this:
 /ubuntu.images/ubuntu-natty-11.04-i386-server-20111003

which would match both
 099720109477/ebs/ubuntu-images/ubuntu-natty-11.04-i386-server-20111003
and
 099720109477/ubuntu-images/ubuntu-natty-11.04-i386-server-20111003

This changes the search to explicitly skip names matching the '/ebs/' token

alpha builds do not get version number

This reverts the change made in revision 398.
Alpha builds do not contain a version number, while beta and RC builds do.
