Draft Different configuration options to turn logging On/Off for explicit entities and users

For integrating the Logging Framework, following are the configuration options using which we can turn logging on or off for explicit entities and users:

1. The common thing that needs to be added to see logging on or off for explicit entities and users is,

   <add key="serilog:using:FilterExpressions" value="Serilog.Filters.Expressions" />

2. To turn logging On/Off for explicit entities or classes,
   1. To turn On, add the following configuration keys,

      <add key="serilog:filter:ByIncluding.expression" value="SourceContext = 'GenericEntity'" />
      Where 'Generic entity' is just an example of a class name for which you want to see logging.

   2. To turn it Off, you just need to remove the above-mentioned configuration key from the file.
3. Turn logging On/Off for explicit users,
   1. To turn On, add the following configuration keys,
      <add key="serilog:filter:ByIncluding.expression" value="UserName = 'TestUser'" />
      Where 'TestUser' is just an example of a username for which you want to see logging.
   2. To turn it Off, you just need to remove the above-mentioned configuration key from the file.
