Committed SIDIntegrationTests.java which so far contains tests for getSystemMetadata for 18 cases we've come up so far for resolving a SID into a PID.
Contains setup methods for each scenario, hopefully reusable for other tests beyone getSystemMetadata.
The testGetSystemMetadata method uses the setup methods, calls getSystemMetadata with a SID, and then checks if the returned metadata's PID matches what we'd expect.
Also overrode the createTestObject method in ContextAwareTestCaseDataOne, split into two methods, one to be usable by the tests.
refs #6725

Continued implementing SID-related integration tests (SIDIntegrationTests renamed to SidCommonIT and lots of functionality rewritten, SidCNIT and SidMNIT added for CN/MN-specific tests). Moved some CN/MNCallAdapter code into CommonCallAdapter. Reverted some changes to ContextAwareTestCaseDataOne because the functionality made more sense in SidCommonIT.

Just a few fixes and some reorganizing for the SID-related integration tests

refs #6725

Moved updateSystemMetadata() from CN/MNCallAdapter into CommonCallAdapter.

Made improvements to SidCommonIT, SidCNIT, and SidMNIT - abstracting out a few parameters, making tests more readable, etc.

Realized the modifications to ContextAwareTestCaseDataone.createTestObject() were contradictory to the API - obsoletes or obsoletedBy cannot be part of the SystemMetadata at the time of creation. Fixed method signatures.

Also fixed a bug in CNCoreTestImplementations.

Split the existing SID test classes into CN, MN, and a common class (SidCN/MNTestImplementations, SidCommonTestImplementations)
Since we're expecting imminent validation on the V2 API methods, the existing PID chain setup methods (for the 18 cases we've recorded) don't make sense for MNs. So I split the setup methods into the CN/MN test implementation classes with the existing ones being the CN setup methods. I wrote new test scenarios for the MN case.

Changing all SID-related tests to match our existing format:
- chanaged the Sid test classes from test classes to Sid*Implementations.java, so it can be used in composition
- created *TestDefinitions.java interfaces for SID-related tests, split up by the API they belong to
- added these ^ interfaces to the *V2IT.java test classes
- added the Sid*Implementations classes as members of the *V2IT.java test classes

Implemented Rob's new test annotations on the new SID tests, and started adding them to the existing tests.

Working on implemented Rob's new test annotations on the existing tests: added them to CNCoreTestImplementations.

Refactored the v1-v2 type conversion out of the CommonCallAdapter, added methods for converting in the reverse direction.

Went through all tests in ReadTestImplementations, CNReadTestImplementations, and MNReadTestImplementations and added WebTestName and WebTestDescription annotations to them.
