Support configurable emulator screen resolution

[jnhyperion]

Added emulator screen resolution configuration options in interactive mode.

• Would you mind moving the UI pieces to emu_downloads_menu.py?
• Would it be useful to have a set of default devices? (Pixel2, Pixel3, etc?) right now we have no way of specifying width/height/dpi from commandline.

  OK.
• Would it be useful to have a set of default devices? (Pixel2, Pixel3, etc?) right now we have no way of specifying width/height/dpi from commandline.

I thought about it before, there are 2 reasons why I prefer to enter width/height/dpi from command line:

1. user could have some requests of customized devices, they have various width/height/dpi, we can not list all the hardware profile
2. Pixel2 is hard coded in many code pieces, make it a variable will have many modifications

What do you think?

You are absolutely right. I should have prefixed it with would you like us to make those changes (different device profiles)

@pokowaka sure, it would be great.

@jnhyperion — thanks for the contribution, and apologies it sat without action for so long. Closing rather than asking for a rebase because the right path forward looks different from the implementation here:

• The diff patches emu/templates/avd/Pixel2.avd/config.ini, which was renamed to MediumPhone.avd/config.ini in templates: rename the AVD from Pixel2 to MediumPhone #402 (merged today) — so a mechanical rebase can't recover that file.
• The non-interactive emu-docker create (which most automation uses) wouldn't get the feature with the current shape; a CLI flag like --screen-resolution WxHxDPI usable from both flows would be more broadly useful, and wouldn't need the new consolemenu dependency.
• A few unrelated changes (iputils-ping install, commented-out EXPOSE 5554 / EXPOSE 8554 — those ports are actively used) would need to be split out separately.

If configurable resolution is still useful to you, please open a new issue describing the feature request — a CLI-flag-based approach usable from both the scripted and interactive flows. Small enough that anyone (including a fresh attempt by you) could pick it up.

The code and instructions have changed substantially since this was filed, so a fresh thread will be easier to track.
