Add Shared Storage Abstraction

[FelipeGuzmanSierra]

Context

Currently, the shared storage doesn't have an abstraction defined on the project. The read-or-write process for each BOT defines a Read-or-write module depending on the shared storage service used for the BOT.

A better approach would be defining an abstraction of the shared storage, where the read or write process is already defined depending on the used service.

We need to define this abstraction following this pattern:

# Shared storage base abstraction
module SharedStorage
  class Base
    def initialize
    end
 
    protected

    def read
      # Depends on the service (PostgreSQL, MySQL, S3, kafka, etc...)
    end

    def write
      # Depends on the service (PostgreSQL, MySQL, S3, kafka, etc...)
    end
end

For this:

• Define the base file for the abstraction
• Define the shared storage PostgreSQL implementation.
• Update the BAS bots to use the read and write method defined on the assigned shared storage.
• Update tests
