Outbound Mail endpoint prototype

[teosarca]

Prototype outbound email endpoint for metasfresh/metasfresh-webui-frontend-legacy#836

Note to IT

• full regression test on Swing EMail sending is needed (also open it from different documents)
• full regression test on text templates is needed
• besides those regression tests, pls test the frontend task

[teosarca]

API changes (please check swagger for details)

• /mail/templates endpoint which returns a list of key/value templates which user can pick from a dropdown and apply them to current email
• to apply a given template you shall use the regular PATCH operation with path="templateId", value={ templateId : templateName }

API is ready for frontend implementation

Changed the mail configuration on w101:

update AD_SysCOnfig set Value='-' where name='org.adempiere.user.api.IUserBL.DebugMailTo';
update AD_Client set SMTPHost='localhost', IsSmtpAuthorization='N' where AD_Client_ID in (0, 1000000);
update AD_User set EMail='it@w101.metasfresh.com' where AD_User_ID=2188223;
/*
select name, value from AD_SysCOnfig where name='org.adempiere.user.api.IUserBL.DebugMailTo';
select AD_Client_ID, SMTPHost, IsSmtpAuthorization from AD_Client;
select AD_User_ID, login, Email from AD_User where Login='it';
select * from AD_MailBox;
*/

Tested on w101, using only the mail API:

1. Create a new email for current user, having C_Order_ID=1005626 in context

curl -X POST --header 'Content-Type: application/json' --header 'Accept: application/json' -d '{ \ 
   "documentPath": { "windowId":143, "documentId": 1005626} \ 
 }' 'http://w101.metasfresh.com:8081/rest/api/mail'

2. Send the email (assuming mandatory email fields like To was filled automatically on previous request).
   Also assuming the emailId returned on previous call is 1".

curl -X POST --header 'Content-Type: application/json' --header 'Accept: */*' 'http://w101.metasfresh.com:8081/rest/api/mail/1/send'

To be tested together with metasfresh/metasfresh-webui-frontend-legacy#836 when it is finished as well.
