Add a `UriRandomizer`

[TonyTroeff]

Describe your idea
I need something ready that should be able to generate me random Uris.

[sameerfairgoogl]

Should we expect the Uri to be a certain length, or are we expecting the length of the Uri to be random as well?

[TonyTroeff]

It should be random - for this purpose we should use the RandomizationHelper.GetRandomString() method.
Of course, the Uri must be valid at the end so some kind of encoding or character set limiting should be implemented as well.

As a subsequent issue, we will make the randomizer controllable by providing the following parameters passed during instantiation:

• With path
• With query
• With fragment
