Processor registration restructure

[Niraj-Fonseka]

[ Current ] -

• Currently whenever a collector comes alive it will call home to the finance manager with a payload with the url and the type of the bank.

[ Changes Needed ] -

• we should configure saving the urls in the postgres database instead of the redis database. And have a post endpoint for registering them.
• Therefore whenever someone writes and deploys a processor they can do a post to register the collector
• We can maintain the processor health checks and all that the same
