Add user affordance for scanner modules that can create a new session

[dwelch-r7]

Adding some messaging to the end of scans to tell the user how many credentials and/or sessions were successful
We can potentially flesh this out further in the future by printing out a table of the good creds/created sessions and extending this more broadly to all scanner types but we've limited the scope to just the login modules for the new SMB, and SQL session types for now

Verification Steps

• Boot up framework
• Use the smb_login module
• Perform a single run against a set of hosts with CreateSession set to false
• Repeat above but for CreateSession set to true
• Verify the output messages are correct (correct number of good creds/sessions etc)
• Repeat for postgres_login, mssql_login and mysql_login
