When validating a discriminated union where the union value has been
passed as a Pydantic model instance, we should access the discriminator
field value using the field name and not the field alias (whether one is
set or not).
* Descriptive exception for incorrectly defined validator fields.
Throws a ConfigError wth helpful feedback if a validator is passed incorrectly defined fields.
* Minor grammar correction.
* Expanded example.
* Added test for bad validator decorator fields.
* Added changes .md file.
* Improved wording in error message.
* Test fix.
* Update pydantic/class_validators.py
Encloses expression into a list comprehension.

* Add MongoDsn to pydantic.networks with allowed_schemas and get_default_parts
* Add unit test to MongoDsn and remove default host from default parts becouse it's required by MongoDB protocol
* Fix import issues, follow contributing guide
* Add changes to docs
* Add changes to changelog
* Allow ellipsis on Fields within annotated types
The usecase is TypedDicts, which can't have default values otherwise.
Meaning that adding Optionals to Annotated drops them from the list of
required fields, which the patch fixes.
* Add test for TypedDict required optionals
Clarifies what's required with TypedDicts schemas.
* Add description of changes
* PR feedback
* extra tests as requested

* Avoid __dict__ and __weakref__ attributes in AnyUrl and _BaseAddress subclasses
When inheriting from a class with `__slots__`, [child subclasses will get a `__dict__` and `__weakref__` unless they also define `__slots__`](https://docs.python.org/3/reference/datamodel.html#notes-on-using-slots).
```python
from pydantic import AnyUrl, AnyHttpUrl
class AnyOtherHttpUrl(AnyUrl):
allowed_schemes = {'http', 'https'}
__slots__ = ()
print(set(dir(AnyHttpUrl)) - set(dir(AnyUrl)))
#> {'__weakref__', '__dict__'}
print(set(dir(AnyOtherHttpUrl)) - set(dir(AnyUrl)))
#> set()
```
