Feature: change @Id to save _key instead of _id

[mvollmary]

Currently a field annotated with @Id is saved as _id in ArangoDB. Since this field is more for internal usage and does not offer any benefit to the user, we should change @Id to represent the document field _key instead, like @Key currently does. This eliminates the need of having two fields (for @Id and @Key) when using user generated keys.

Hi, Will this also be added to the 1.x.x branch? (I haven't upgraded spring data yet)

[mvollmary]

Hi @sigh-man,

because this is a breaking change we have only planned to provide this with the upcoming major release 3.0.0.

[sigh-man]

OK - Thanks. I assume the arango-spring-data 3 will require spring-data 2 ? - I guess I'll just have to get on with upgrading spring ... (been meaning to anyway)

[mvollmary]

Yes, arangodb-spring-data 3 will require spring-data 2

Implementation done. Feature will be included in the upcoming 3.0.0 release
