1) Type Safe checking on correlation properties (no more str())
2) A running workflows Correlations are once again at the key level.
# Backend
1) Both send and receive messages can have correlation_keys - and we compare these to each other to quickly assure a match (if they both exist - otherwise we fall back to comparing the properties on the receive to the sending messages payload)
2) Cleaned up the migrations to just one file
Adding a correlation cache - so we have a reference of all the messages and properties (though still lacking a description of keys)
Adding yet another migration, maybe should squash em.
* SpiffWorkflow did not serialize correlations - so they were lost between save and retrieve.
* When comparing Correlation Property values - we are storing these values as strings in the database and can't convert them back to integers later, so I'm changing everying everywhere to compare after conversion to a string. Don't feel great about this one.
* By using an SQL Alchemy join table, there is a lot of db queries we don't need to write.
* A few handy fucntions on db models to make it easier to work with correlations.
* Updated tests because I changed some of the BPMN models we were testing against.
* Database migration to use the new constraint names with the alternate form of the join table between correlation mesages to instance messages.
* Link between message instance and correlations is now a link table and many-to-many relationships as recommended by SQLAlchemy
* Use the correlation keys, not the process id when accepting api messages.
Request "profile" scope over OpenID so we can get a few more bits of information when avilable.
Add a "clear_perissions" script
Add an "add_permissions" script
Add an "add_permissions" script
When logging in for the first time, check for any awaiting permissions and assign them.
Add "enumerate" as a whitelisted function to React Schema
Add a "display_name" to the user table
Add a test for adding a new permission
Add a test for adding a user to group
Adding a test for deleting all permissions.
Adding a display name for the user table
Request email from open id clients, as this would provide a handy way to uniquely reference users when assigning to groups.
During Login do a lookup on email if possible -- so that permissions assignments based on email can be connected when sigining in through openid.
Don't use "open_id" for the service name on user accounts, use the iss string provided through open id, this will allow us to support more than one open id platform.
Update the KeyCloak configuration so it is able to return email addresses for users -- which will make permission assignment easier in the future.
Removed several unused commands in the user_service class.
