Disallowing selected types of a namespace

[realvizu]

Make it possible to disallow selected types of a namespace.

Example use case: to prevent developers using the Assert type of Xunit and use FluentAssertions instead.

I can think of two different ways to specify this in the config: the first aligns better with an allowlisting approach, while the second fits more with a denylisting approach.

Allowlist approach:

<NsDepCopConfig IsEnabled="true" ChildCanDependOnParentImplicitly="true">

    <Allowed From="*" To="FluentAssertions">
    <Allowed From="*" To="Xunit">
        <DisallowedMembers>
            <Type Name="Assert" />
        </DisallowedMembers>
    </Allowed>

</NsDepCopConfig>

Denylist approach:

<NsDepCopConfig IsEnabled="true" ChildCanDependOnParentImplicitly="true">

    <Allowed From="*" To="*" />

    <DisallowedMembers OfNamespace="Xunit">
        <Type Name="Assert" />
    </DisallowedMembers>

</NsDepCopConfig>

@realvizu In the above-mentioned code, the closing tag for DisallowedMembers is wrong!

<NsDepCopConfig IsEnabled="true" ChildCanDependOnParentImplicitly="true">

    <Allowed From="*" To="*" />

    <DisallowedMembers OfNamespace="Xunit">
        <Type Name="Assert" />
    </DisallowedMembers>

</NsDepCopConfig>

Corrected it, thanks!
