docs(CHANGELOG): update changelog with 1.2.27
docs(ngModelController): update wordings, add more general info

The wordings in setDirty etc. were specific to inputs, but ngModelCtrl
is agnostic to this and the preferred term is 'control'. I also
added some more info about this to the description, and linked to
the example that now lives at the bottom of the page.
docs($httpProvider): add info about `defaults.cache`

Closes #10134
fix(input): call $setTouched in blur asynchronously if necessary

If the model is blurred during an apply it should trigger
$setTouched asynchronously.

Fixes #8762
Fixes #9808
Closes #10014
chore(scripts): publish 1.2.x releases to npm with correct tag
docs(ngAnimate): Fix typo

The ngAnimate makes reference to a function `$animateProvider.classNamePrefix`
that does not exist, the correct function is `$animateProvider.classNameFilter`

Closes #10142
chore(scripts): fix 1.2.x tag name
