Update: Add Zoom meetings client w/ custom configs

[n3philim]

Issues: we need to use the IT installer since it appears to be statically versioned -- i.e. current download path is https://zoom.us/client/4.4.52595.0425/ZoomInstallerIT.pkg instead of https://zoom.us/client/latest/Zoom.pkg which we won't be able to sha check consistently without some sort of magic

@luciusbono if you've got time before EOW this week can we discuss if we want to push down a custom config plist as well, and what we want to set on it? Also, I notice that we don't really have any other downloads that are non-dmg'd packages, will this be a gotcha?

PKG should work fine, we've had them in the past and it's a valid install primitive in dinobuildr. I'm OOO until next week, but Zoom's documentation is weak around those options so I don't have any specific guidance other than I'd like the following:

ZAutoUpdate enabled (even though we don't know what it does)
And then disabling all the unsupported login types.
It seems like some of the options could make the SSO experience a lot less confusing.

Ideally, we'd also deploy this plist to regular clients, but that'd require a signed package.

Minimum viable Zoom was deployed in #160 -- we should dig into the potential benefits of the IT pkg + plist in a while when things have calmed down a bit.
