Duplicate schema BCCEmailArchive in esignature v2.1 API

[lbilger]

In the v2.1 API, there is a schema called BCCEmailArchive that is not referenced anywhere. It seems to be a duplicate of bccEmailArchiveHistoryList. There is also another schema called bccEmailArchive that is referenced. I think BCCEmailArchive should be removed.

Using the OpenAPI Generator to generate Java code on a non-case sensitive file system (e.g. on a Mac) will produce a file BCCEmailArchive.java containing the public class BccEmailArchive which is not allowed and causes compilation to fail.

Workaround: add an ignore file that ignores BCCEmailArchive.java.
