Suggestion: add `sv_mincmdrate` and `sv_maxcmdrate`

[gundogfan]

Since there are sv_maxrate, sv_minrate, sv_maxupdaterate and sv_minupdaterate, for rate and cl_updaterate, I was wondering if there's a possibility of including sv_maxcmdrate and sv_mincmdrate for cl_cmdrate.

In case this is possible and included, I'd say a good default value for sv_mincmdrate would be 65, and for sv_maxcmdrate 255 which I've tested using 60 and 250FPS and according to net_graph it works fine.

Of course it is a good idea to have the commands.
