This commit also changes the config files and their layout to
(reasonably closely) match what the cli would generate for a new app.

The exact messages depend on the timing of several events and may vary
between runs. This occasionally causes flakes on CI.
This commit reduces the risk of flakes by loosen the conditions to only
check for what we actually care about.

This minimises the risk of unexpected failures due to breaking changes,
when building a new image (e.g. as a result of an unrelated config
change in Dockerfile).
PR Close#29976
Previously, the preview server docker image was based on Debian 8
(jessie). Recently, `jessie-updates` and `jessie-backborts` were removed
from the Debian mirrors ([more info][1]), thus breaking new builds of
the image.
Instead of updating `/etc/apt/sources.list` to remove the obsolete
sources, this commit upgrades to Debian 9 (stretch).
(The GCE VM running the preview server docker container was also
upgraded from Debian 8 to 9 this morning.)
---
Other changes:
- Removed dependency on `chkconfig`, which is not supported on Debian 9.
- Installing `nginx` from the regular repositories (instead of
`*-backports).
- Upgraded to `pm2` v3, which can handle hooking itself up to system
startup better (without `chkconfig` - see above).
- Updated tests to reflect the fact that `nginx` has dropped the reason
phrase in response status lines for HTTP/2 (in compliance with
[the spec][2]). (HTTP/1.1: `HTTP/1.1 200 OK` | HTTP/2: `HTTP/2 200`)

In #29926, the size of the build artifacts has increased due to turning
on differential loading (which generates an es2015/es5 pair for each JS
resource).
To avoid the preview server's rejecting the build artifacts (as in
[288181][1]), this commit increases the max allowed artifact size from
20MB to 25MB (current artifact size after #29926 is ~22MB).

In #29953, the wait period for SW on localhost was increased to avoid CI
flakes for the PWA score tests.
This commit expands the fix to non-localhost origins to avoid flakes in
the `aio_monitoring` job, when CircleCI VMs/network are slow.

In light of #29926, that will change the path of `tsconfig.app.json`,
this commit switches from a hard-coded `tsconfig.app.json` path to
looking it up in `angular.json` (to be more future-proof).
PR Close#29989
Previously, the `build-with-ivy` script could be used to build the `aio`
project with Ivy (once it had been prepared with `ivy-ngcc`, etc.) and
then restored the configuration (e.g. `tsconfig.json`) to non-ivy mode.
As a result, it was not useful for running other commands (e.g. unit/e2e
tests) in Ivy mode.
This commit renames the script to `switch-to-ivy` and employs a
different model (similar to `ng-packages-installer`), where the project
is setup to run in Ivy mode and then all subsequent commands are
executed in that mode (until restored).
Since this is currently only used on CI, there is no automatic way to
switch back to non-ivy mode (but it could be implemented in the future
if needed).
Finally, the script now modifies `src/tsconfig.app/json` instead of
`tsconfig.json` to ensure that the `angularCompilerOptions` are not
ignored/overwritten. This is also closer to what the cli generates
with the `--enable-ivy` option.

The server used for testing on localhost has less optimizations (e.g.
serves uncompressed files), so we need to wait longer the ServiceWorker
to be loaded and registered to allow Lighthouse to reliably detect it,
especially on slower environments (e.g. CI).
