`Component` selectors are always kekabed while `Directive` selectors are always camelized. This updates the lint rules to convert the prefix to the appropiate case
Fixes#13796
Usage:
```
ng new foo --experimentalIvy
```
Users will need to use `ngcc` so to process code coming from NPM and produce the equivalent Ivy version. This needs to be done once after installing the node packages.
```
node_modules/.bin/ivy-ngcc
```
`ngtsc` compilter will then be used when building using the `--aot` or `--prod` flag.
Fixes#13024
This aligns options that do the same thing:
1) `skipSpecs` and `spec` has been deprecated in favor of `skipTests`.
2) `styleext` has been deprecated in favor of `style` since the latest is two words.
Fixes#12784
* fix(@schematics/angular): --minimal should prevent generating e2e
Don't run the e2e schematic when using application or ng-new schematics
with option.minimal set to true.
fix#12739
* style: inverse logic according to feedback
* test(@schematics/angular): app and ng-new --minimal shouldn't generate e2e
This should clean up the code a bit.
Note: at first I added the no-useless-cast rule, but after getting frustrated
with it (as it has many false positive), I decided to remove the rule but some
useless casts were removed so I let those in the PR.
