ssl_no_verify flag

[pauhidalgo]

When calling bucky data sync, we have to checkout a number of git repos (done via subcommands) and use urllib to download some other data sources.

We should add a flag to the cli (either at the root level so bucky [-flag here] subcommand or as part of the data subcommand bucky data [-flag] sync] that will disable all ssl verification in the calls to urllib and the cmdline execution of git that occurs in https://github.com/mattkinsey/bucky/blob/poetry/bucky/util/data_sync.py

Kate added this to the old data pulling script so she can point you to the correct context to use to wrap the urllib calls.
