"Default" State of Switchport in documentation is confusing

[FredPocai]

Documentation states "default state" is "no switchport". I believe the documenetation intends to state this is the default state of the interface, but this is not the default behavior of the template.

dellemc.os10/roles/os10_interface/README.md

Line 29 in 9946fc3

| ``switchport`` | boolean: true,false\* | Configures an interface in L2 mode | os10 |

However, the "no switchport" command is not applied if the "switchport" key is not present in the os10_interface dict....unless "portmode" is set (which is a bit counterintuitive).

Taking this section of the template to an online jinja parser:

{ "intf_vars": { "portmode" : "" }} renders "no switchport"
{ "intf_vars": {} } renders nothing.
