CORDA-696 - Create separate transaction types for contract upgrade transactions (#2589)

Browse Source 
* CORDA-986 and CORDA-985 CompositeKey and Signature verification performance fixes (#2467)

* CORDA-696: Create separate transaction types for contract upgrade transactions.

Add rationale around upgrade transactions

Move contract upgrade transaction resolution logic into internal until it's stabilised.

Throw a better exception when contract attachment not found

Default legacy contract constraint to always accepting - needs to be changed to whitelist constraint before merging

Introduce a new upgraded contract interface that allows specifying the legacy constraint.

Remove StateLoader, make all tx resolution functions take in ServicesForResolution

Contract upgrade transactions can handle whitelist by zone constraints

When creating a contract upgrade transaction, make sure the attachment of the old cordapp gets attached when using hash constraints.
Attachment lookup for a given contract class name only scans currently loaded cordapps, and we don't load old versions of cordapps.
