Add remove_proxies API for pallet-proxies

[xlc]

Add a pub API to remove all the proxies so other pallets can call this.

substrate/frame/proxy/src/lib.rs

Lines 306 to 310 in 69198d1

	fn remove_proxies(origin) {
	let who = ensure_signed(origin)?;
	let (_, old_deposit) = Proxies::<T>::take(&who);
	T::Currency::unreserve(&who, old_deposit);
	}

I want to take up this as my first substrate issue. Would you please mind explaining a little on this issue for me to get started ?

Verify similar to remove_proxy

substrate/frame/proxy/src/lib.rs

Lines 286 to 293 in 69198d1

	fn remove_proxy(origin,
	delegate: T::AccountId,
	proxy_type: T::ProxyType,
	delay: T::BlockNumber,
	) -> DispatchResult {
	let who = ensure_signed(origin)?;
	Self::remove_proxy_delegate(&who, delegate, proxy_type, delay)
	}

Add new method pub remove_all_proxy_delegates, move the logic there, call this method from remove_proxies.
