Autogenerated Parameters

As an atomicapp developer I would like to be able to define some parameters which are autogenerated from a pattern So that I can avoid having to provide values which are only used to connect two containers.

Use Case Example:

When creating internal only databases, the database server and consumer must agree on username/password or client/server certificates, but the precise values are unimportant because they are only used internally. I would like to be able to have

Nulecule specification change:

params:
  - name: dbuser
  - description: The name of the database read/write user
  - generate: "expression"
  - from: <RE pattern>

generate directive - indicate that this is a dynamically generated value

This could be a time stamp, or an RE expression or a random number or some other dynamically created value type

The first acceptable value would be "expression" but others are possible
from directive

With the "expression" value of the from directive, this provides the pattern to use to produce a random value
