0e9a54e9a9 Python: Rename WeakCrypto to WeakCryptoKey 
Since WeakCrypto always makes me think that it's about all weak crypto (like
using MD5, or completely broken ciphers such as ARC4 ro DES) and not just about
weak key generation.

46ad611d57 Python: Port py/weak-crypto-key to use type-tracking 
instead of points-to.

Looking at query results also made me realize I didn't supply a very good
"origin" for ECC in cryptography package, so I improved that 👍 -- maybe that
sohuld have been split into multiple commits... too late :(

* Added DSA constants (they are just accidentially the same as RSA right now)
* Removed FakeWeakEllipticCurve and used a real weak elliptic curve instead

a19da54c9e Python: Exclude flask.request imports as RemoteFlowSource 
When I changed the taint modeling in 19b7ea8d85, that obviously also means that
some of the related locations for alerts will change. So that's why all the
examples needs to be updated.

Besides this, I had to fix a minor problem with having too many alerts. If
running a query agaisnt code like in the example below, there would be 3 alerts,
2 of them originating from the import.

```
from flask import Flask, request
app = Flask(__name__)
@app.route("/route")
def route():
    SINK(request.args.get['input'])
```

The 2 import sources where:

- ControlFlowNode for ImportMember
- GSSA Variable request

I removed these from being a RemoteFlowSource, as seen in the diff.

I considered restricting `FlaskRequestSource` so it only extends
`DataFlow::CfgNode` (and make the logic a bit simpler), but I wasn't actually
sure if that was safe to do or not... If you know, please let me know :)

cf9ad0cdc5 Python: Move ExternalAPI queries back under Security 
This was raised as a question at review, and I don't really have a good enough
argument for moving it under POI. At the end of the day, they are _security_
related enough I guess :)

2632422783 Python: Add FP test for unknown argument in string format 
Reported in https://github.com/github/codeql/issues/2650

I found this during a bit of spring cleaning in my working
directory. As this doesn't have any immediate security implications, I
don't know when we'll get round to fixing it, but it can't hurt to
have the test case checked in.
