Support for device customization

[ericdallo]

Currently i need to update the $AVD_HOME/.avd/device.avd/config.ini with the custom configs that I want like:

image.sysdir.1=system-images/android-28/default/x86/
tag.display=Default
tag.id=default
hw.gpu.enabled=yes
AvdId = Nexus_5X_API_29
PlayStore.enabled = true
abi.type = x86
avd.ini.displayname = Nexus 5X API 29
avd.ini.encoding = UTF-8
disk.dataPartition.size = 6442450944
fastboot.chosenSnapshotFile =
fastboot.forceChosenSnapshotBoot = no
fastboot.forceColdBoot = no
fastboot.forceFastBoot = yes
hw.accelerometer = yes
hw.arc = false
hw.audioInput = yes
hw.battery = yes
hw.camera.back = virtualscene
hw.camera.front = emulated
hw.cpu.arch = x86
hw.cpu.ncore = 4
hw.dPad = no
hw.device.hash2 = MD5:ae200ad6786ec467cb9067f7b46b0fd1
hw.device.manufacturer = Google
hw.device.name = Nexus 5X
hw.gps = yes
hw.gpu.mode = auto
hw.initialOrientation = Portrait
hw.keyboard = yes
hw.lcd.density = 420
hw.lcd.height = 1920
hw.lcd.width = 1080
hw.mainKeys = no
hw.ramSize = 1536
hw.sdCard = yes
hw.sensors.orientation = yes
hw.sensors.proximity = yes
hw.trackBall = no
runtime.network.latency = none
runtime.network.speed = full
sdcard.size = 512M
showDeviceFrame = yes
skin.dynamic = yes
skin.name = nexus_5x
skin.path = /home/greg/Android/Sdk/skins/nexus_5x
tag.display = Google Play
tag.id = google_apis_playstore
vm.heapSize = 228

There is some way to do that?
