Create API-M BOSH Release for Deployment Pattern 4

[imesh]

Description:
A BOSH release might need to be created for each API Manager deployment pattern to allow them to be used in production environments. Currently, we have one BOSH release implemented for orchestrating one API-M node and one API-M Analytics node. We might need to update the folder structure of this Git repository and create a new BOSH release for API-M deployment pattern 4 according to [1].
