[TF2] Feature Request: Add back -tickrate argument to servers

[ldesgoui]

Hello,

Recent tests (https://github.com/ldesgoui/mms-unlocked-tickrate) concluded that the -tickrate commandline argument could be pulled back into TF2, however:

• Wrangled Level 2 and 3 Sentries have higher firerate (linearly to how high the tickrate is)
• Dynamic objects (weapons, demo grenades, etc) are very bouncy
• Wallbugs are more frequent

Thanks
