Add github:contain-rs:owners as an owner to all crates

[Gankra]

Yay new features!

[Gankra]

I've added those that were checked out on my machine:

bit-set     
cons-list   
linked-hash-map 
raw-vec     
trie
bit-vec     
enum-set    
linked-list 
rust-traverse
linear-map  
lru-cache   
vec-map

Notably not blist as I lost ownership of this crate to @steveklabnik when proofing out an exploit and never got it back.

bug fixed in cargo, blist reclaimed.

Can this be closed now?

[Gankra]

Still need, par-vec, interval-heap, bst, compare, ordered_iter, string-joiner, I think.

This is now github:contain-rs:publishers because Github changed how teams worked and forced owners to be renamed. 😡 💢 💢

All crates probably need to be updated again.
