Fix #734: add extra field on project

[junoyoon]

This includes the fix for #734 "add extra field on project

To support extra field, I have modified org.openstack4j.openstack.identity.v3.domain.KeystoneProject like followings.

• Put private Map<String, String> extra = new HashMap<String, String>(); in the KeystoneProject
• Create getExtra / setExtra with @JsonAnyGetter and @JsonAnySetter which are called when there are no explicitly mapped field.
• Ignore is_domain field in setExtra which is automatically calculated field from keystone. Currently openstack4j just ignores this field. However with this patch if we don't ignore this in setExtra, it will be re-sent to the keystone during project update call and keystone will keep this in DB's extra fields.
• Put @JsonIgnore on getLinks(), because if it's re-sent to keystone while project update, it will be interpreted as extra field just like is_domain.
• Put @JsonIgnoreProperties(value = "extra" , ignoreUnknown = true) on KeystoneProject class. If we don't provide this on KeystoneProject class, private Map<String, String> extra = new HashMap<String, String>(); will be translated to "extra": { .... }. This is not working in IdentityV3. Puting @JsonIgnore on private Map<String, String> extra = new HashMap<String, String>(); doesn't not working for @JsonAnyGetter and @JsonAnySetter as well. I found that this is the only way not to send extra field to keystone.

You can not find the exact blueprint for this in keystone but I can find relevant the blueprint in horizon.

Because it's only visible when the additional field is input, there is not much examples in OpenStack IdentityV3 spec.

You can fine the some evidence in the following. is_domain field.

Hi @junoyoon,
Could you paste a link to the documentation of the feature above in the idv3 api?

@auhlig Added.

@junoyoon Thanks. I initially was aware of the is_domain but not of the extra field.
