Pull request overview

This PR extends the Mikrotik RouterOS 7 platform support by enabling GRE tunnel interface generation in the RouterOS7 initial configuration template and advertising GRE tunnel capability (including transport VRF) in the device feature matrix, with accompanying documentation updates.

Changes:

• Added RouterOS 7 GRE tunnel interface creation/config handling in the initial device template.
• Declared RouterOS 7 support for GRE tunnels (IPv4/IPv6/VRF) in the device feature metadata.
• Updated documentation for GRE tunnel plugin support matrix and static routing platform table.

File	Description
netsim/devices/routeros7.yml	Declares RouterOS 7 tunnel/static-routing capabilities and interface naming support.
netsim/ansible/templates/initial/routeros7.j2	Adds GRE tunnel interface creation and ensures tunnel interfaces are handled when setting interface attributes.
docs/plugins/tunnel.gre.md	Marks Mikrotik RouterOS 7 as supported for GRE over IPv4/IPv6 with transport VRF.
docs/module/routing-static.txt	Adds RouterOS 7 to the static routing support table (and includes a platform-name typo).

I'm guessing you forgot to add new files to the PR. Here's what I get when trying to start the test lab from your branch:

[ERRORS]  Errors found in 01-gre.yml
[WRONG]   configs: Cannot find routing configuration template for dut/device routeros7
[HINT]    Use the '--debug template' option if you're troubleshooting custom configuration templates
[WRONG]   configs: Cannot find tunnel.gre configuration template for dut/device routeros7

Also, PRETTY PLEASE NEVER EVER add some random new functionality into a somewhat unrelated PR. The PR is really about GRE tunnels, static routes, and discard static routes.

Submit the static route part (thank you for adding that!) as a separate PR, then when that one is merged, rebase this PR on the dev branch (so you'll get just the tunnel related changes) and reupload it (usually using git push --force).

sorry about that with the static routing..

I was jumping around a bit to much in my trees and normally have bunch of uncommitted files..

Think i really need my own 'pre push' hook that verifies everything in a brand new tree =/

I will make the new PR for that now and remove the change from this one.
