Update Marketing Channels Classification interface to remove references to First/Last Touch Marketing Channels

[#1]

Description - 

Replace First and Last Touch Marketing Channels (and their associated Marketing Channel Detail) fields with a single, generic Marketing Channel (and its associated Marketing Channel Detail) field

Why is this feature important to you -

First and Last Touch Marketing Channels have been deprecated in Adobe Analytics, so there is no need to continue making that distinction in the user interface. Furthermore, for users who are familiar with the generic Marketing Channel dimension, showing First and Last Touch Marketing Channels in this UI is confusing.

Also, the Help documentation also says that in the current interface, either First or Last Touch Marketing Channel can be selected for classification, since classifying one impacts the other too. So showing First and Last Touch Marketing Channel in the UI is redundant.

How would you like the feature to work -

Replace both First and Last Touch Marketing Channel (and their associated Marketing Channel Detail) fields with the single, generic Marketing Channel (and its associated Marketing Channel Detail) field.

Current Behaviour -

The Marketing Channels Classification UI shows the option to classify First Touch Marketing Channel and Last Touch Marketing Channel (and their related First/Last Touch Marketing Channel Detail).

+1 to this.  Having recently tried to set up Marketing Channels for a new Adobe client, the documentation and admin console are out of date and confusing. Trying to explain how it works to new users is really difficult.
