Add timeout to avoid long-term hangs

[jamonholmgren]

We've had multiple issues over the years with Ignite hanging forever and people (patiently!) waiting for hours for it to finish.

Examples: #1249, #2084, #1735, #1365, #1287, #172, and many more.

This adds a simple timeout that won't allow Ignite to take longer than 10 minutes once we start spinning up a new app.

This might be a bit too aggressive; I don't know what our longest installs take these days, but I just tried one using npm as the package manager and choosing the DIY option on Ignite v9 and it took roughly 72 seconds, which is 12% of this timeout.

This does NOT need to be merged prior to v9, but can be; it's a relatively small change.

Looking good! Left some comments.

Will also time an install with npm/yarn on an older intel machine to see how the 10 minutes buffer is (should be fine, though).

@jamonholmgren one way to avoid the timer being too aggressive, maybe a cli flag to disable it for certain situations? like terrible car/plane wifi or something?

Added a --no-timeout flag!

@frankcalise I'll let you merge when you're ready, if you're ready!
