I want to be able to specify attributes on my class defined in python. This is essential for my specific use case, but I imagine generally useful. I can come up with 3 different situations where it could be useful to add attributes:

1. Attributes on types - This can be done with an annotation
2. Attributes on methods - This can be done with an annotation
3. Attributes on properties - It seems clr.clrproperty needs to be modified to support it.

### from test_clrmethod.py# Attaching attributes to types (1)@clr.attribute(DebuggerDisplayAttribute,"ExampleClrClass: X={X}")classExampleClrClass(System.Object):__namespace__="PyTest"def__init__(self):self._x=3# Attaching attributes to methods (2)@clr.clrmethod(int, [int])@clr.attribute(DescriptionAttribute,"Test method")deftest(self,x):returnx*2defget_X(self):returnself._xdefset_X(self,value):self._x=value# Attaching attributes to properties (3)X=clr.clrproperty(int,get_X,set_X)\        .attribute(DescriptionAttribute,"Gets or sets X")\        .attribute(BrowsableAttribute,True)# Also attaching attributes to properties (3)@clr.clrproperty(int)@clr.attribute(DescriptionAttribute,"Gets Y")defY(self):returnself._x*2

Regarding usingclr.attribte(DebuggerDisplayAttribute, "...") vsclr.attribute(DebuggerDisplay("...")), it is exceedingly hard to infer how an attribute is constructed form the attribute value itself. Instead the list of constructors can be iterated and matched with a list of arguments and this way the best matching constructor can be found.

I can probably implement this myself, but before making a PR I want to know if it will be accepted or it is a bad idea.
