Weapon holster - Extra space only for bringing in another weapon

Add an extra slot space in our inventory where we can put 1 weapon of our choice.
Over time a lot of people have requested that every class could weapon swap as a warrior (which I think is a bad idea and should be unique to warrior) or complained that not every weapon is viable in this or that game mode.

Basically this would allow us to go into a game with 2 different weapons (only 1 equipped, the other one in the weapon holster) and be able to swap depending on the situation, while still suffering the weapon swap stamina affect (the weapon swap stamina effect should probably still be reworked, for example; instead of a full stam out, only allow us to swap weapons for free if we haven’t taken damage for 30 seconds)

I think this could encourage people to learn several weapons on their class, reduce complaints about some weapon being not viable in certain game modes, and encourage variety of gameplay.

Regarding game balance and pvp, this weapon holster would be lost on death just like any other thing in our backpack, but would simply be dedicated to carrying a weapon of any kind.
