Closes#4224 from nchammas/patch-1 and squashes the following commits:
960711a [Nicholas Chammas] [EC2] Preserve spaces in EC2 path
This patch upgrades `spark-ec2`'s Boto version to 2.34.0, since this is blocking several features. Newer versions of Boto don't work properly when they're loaded from a zipfile since they try to read a JSON file from a path relative to the Boto library sources.
Therefore, this patch also changes spark-ec2 to automatically download Boto from PyPi if it's not present in `SPARK_EC2_DIR/lib`, similar to what we do in the `sbt/sbt` script. This shouldn't ben an issue for users since they already need to have an internet connection to launch an EC2 cluster. By performing the downloading in spark_ec2.py instead of the Bash script, this should also work for Windows users.
I've tested this with Python 2.6, too.

This issue was uncovered after [this discussion](https://issues.apache.org/jira/browse/SPARK-3398?focusedCommentId=14187471&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14187471).
Don't change the working directory on the user. This breaks relative paths the user may pass in, e.g., for the SSH identity file.
```
./ec2/spark-ec2 -i ../my.pem
```
This patch will preserve the user's current working directory and allow calls like the one above to work.
