Reduce the verbosity of the ./bin/search index script.

Summary: Currently, the `./bin/search index` script produces a lot of output (one line for every indexed object). Instead, use a `PhutilConsoleProgressBar` to indicate progress. This is much less verbose and gives a real indication of how long the script should take to complete.

Test Plan: Ran `./bin/search index` and verified that a progress bar was output.
