introduced the OperationBuilder

OperationBuilder replaces the old operation handling which was not
built with multiple documents in mind. it uses the new section methods
introduced for each Document and aggregated by the DocumentCollection.

bye bye, LegacyOperationParser!

with this commit we're also finally dropping the snakecase Symbol
conversion for operation names. from here on out we just use the
original names all throughout Wasabi.
fixed incorrect assertion for #soap_action
removed invalid wsdl!

i'm trying to be very correct with this new implementation, while still
being flexible, but this fixture is missing a complete binding.

also the tests only seems to cover the missing message part which the
new implementation already handles.
marked the geotrust spec for operations as pending
