Support regexes when removing znodes about zookeeper HOT 3 CLOSED

Good idea. This may also be useful in other commands. What about introducing a find command with a limited set of operations that could be applied?

For example, to recursively find and remove all nodes whose name begins with foo starting at the path /bar:

find -r foo.* /bar --rm

The implication with --rm is that --force would be implied because it seems impractical to add a conditional version check. I could be wrong here, but that is my intuition.

General syntax of find would be:

usage: find [OPTIONS] PATTERN [PATH] [COMMAND]

PATTERN is a regular expression, either very basic syntax or strictly according to the JDK. PATH is an optional starting path, which defaults to pwd. COMMAND would be a limited set of commands that make sense to apply, where something like --print is the default.

Additional features like find would definitely be good. I'd also suggest having a "verbose" option or inversely "quiet" on the find command such that a consumer can more easily find out what the find command is actually doing (which nodes did it match on such that it is removing them?).

Finished adding support for find command. You can get help with zk --help find. There are also several examples in the README.

Note that this version only supports strict regular expressions as defined by Java 1.6, which means patterns you might expect to work like foo* must be expressed as foo.*. I might add simple pattern matching if this becomes too much of a burden for users.
