[5.7] Allow ENV to control paths of cache files for services, packages and routes

[divand]

In order to override paths of all files in bootstrap/cache, add env vars below:

APP_SERVICES_CACHE
APP_PACKAGES_CACHE
APP_ROUTES_CACHE

env var "APP_CONFIG_CACHE" already defined in commit 578bc83#diff-7b18a52eceff5eb716c1de268e98d55d

Do you have an actual use case for this in your application? If so, can you please describe it.

[divand]

@taylorotwell, sure!
My app has no rights to write to "bootstrap/cache/" and "storage/".
So for "storage/" I'm using this workaround:
in .env:

VIEW_COMPILED_PATH="/tmp"
SESSION_DRIVER="cookie"
LOG_CHANNEL="stderr"

But I cannot override path for "bootstrap/cache/" natively. That's why I suggest to extend the ability to override all of paths which are using to write to fs.

I don't know if this is the best implementation, but in terms of feature I think this is gonna become a must-have sooner or later with the rise of AWS Lambda and the fact that only /tmp is writable.
At the moment, anybody running Laravel on Lambda is doing the changes to the index.php or boostrap/app.php. An environment variable is a much cleaner solution.

@deleugpn this change isn't required to run Laravel (5.8 at least) on Lambda. Trust me... I would know 😉

@taylorotwell I remember going through all your commits on master branch to see if I could find anything related to Lambda when you teased about Vapor. Did I miss it somehow?

@taylorotwell Not missed it. Just think it’s a, “Wait until Laracon” deal.

[deleugpn]

@martinbean I've been battling a lot with getting everything to work on Lambda and I feel like all my efforts are going to be thrown out the window after Vapor release.

@divand @taylorotwell Why this folders not always / default write to the storage folder?
