Remove upper version bounds in all dependencies

[oberstet]

currently, the https://github.com/crossbario/crossbar/blob/master/requirements-min.txt contains a few dependencies with upper version bounds defined. these include:

• urllib3>=1.21.1,<1.27
• idna<2.6,>=2.5
• h2>=3.2.0,<4.0.0: twisted/http2 needs <4:
• hyperframe>=5.2.0,<6.0.0: twisted/http2 needs <6.0.0

can we remove those upper bounds? we should test:

• the CI in this repo
• https://github.com/crossbario/crossbar-binaries

regarding twisted, things are still unchanged with the latest release (though there is a new one upcoming ..): pip install -U twisted[tls,http2]

it is still the same on twisted master: https://github.com/twisted/twisted/blob/2d6a7d6748309b3c199c073c94b84f7f864f8f76/setup.cfg#L91

so actually, in crossbar, we should still have:

h2>=3.2,<4.0
priority>=1.1,<2.0
hyperframe>=5.2,<6.0

[oberstet]

rgd idna, we can remove the upper bound!

idna>=2.4

and rgd urllib3 it should work (now that requests doesn't need a pinning anymore):

urllib3>=1.26.8

so in summary, we can adjust the requirements-min.txt and it should work (hopefully)

h2>=3.2,<4.0
priority>=1.1,<2.0
hyperframe>=5.2,<6.0
idna>=2.4
urllib3>=1.26.8
