Assets transfer between our parachain and other parachains

[serg-temchenko]

As described on the Teleporting Assets page, to move assets between parachains, XCM and the assets teleporting functionality should be used.

In the scope of this task, the mechanism for moving assets should be configured.

Related to Issuer #14.

PR #31 partially sets this up.
With current local setup just testnet, we're able to transfer assets from the Native Chain to our Parachain using extrinsics:
pallet_xcm.teleportAssets.

However, something is misconfigured on a local relaychain node and we cannot receive assets back. I was able to replicated that using the runtimes provided out of the box for asset-hub as well.

As well, teleporting between other system parachains, was not tested. E.g. (AssetHub -> Polka Storage and back).
For now, we're parking this stuff, as it's not critical.

Please do not close this issue until it is fully functioning. For now, it is on hold.
