Provide a "Graylog Schema" Index Set Field Type Profiles as an out of box profile

[drewmiranda-gl]

What?

Using the new "Index Set Field Type Profiles" feature, add an out of box profile that adheres to the Graylog Schema.

Why?

Configuring explicit field types is beneficial to avoid dynamic mapping incorrectly guessing a field type based on the first message in the index with that field. For example a field that should store strings may be incorrectly typed as an integer (or vice versa). Some types are also not possible via dynamic mappings, such as the ip type.

For this reason, providing users with a suggested default mapping that they can apply as they choose, can be very helpful, both for Graylog Open users and also paying customers alike.

So if the customer does use field names that adhere to the schema, they'll be the right data type. Jeen-yus!
