Support for creating and funding linkdrop links

[kcole16]

1. 1. Story

As an app developer, I want to fund the creation of my users` accounts, so they can login and use my app.

1. 1. Flow

1. Generate new key pair (pub key/private key) 2. Call [Linkdrop](https://github.com/nearprotocol/near-linkdrop) contract's send function with public_key as the argument, and an attached NEAR balance 3. Redirect user to the wallet with "fundingKey" argument

1. 1. 1. 1. Unhappy Path

• [ ] Surface error if call to Linkdrop contract fails

@kcole16, this solution just needs to be generalized to near-api-js correct?

@potatodepaulo do we have specific customer who wants to integrate this? If so – I think it will help to do demo for them first and then refactor into library once we have it working end to end.

@vgrichina @mikedotexe @kcole16 do we still need this functionality? PR related to this issue was closed: https://github.com/near/near-api-js/pull/256 Should we close the issue?

I think on client side it's relatively easy, more interesting is to create smart contract SDK which would allow to send more customised linkdrops. Like allow to avoid attaching 1 N for gas fees, allow to transfer NFTs on claim, etc. Basically make it easy to send any kind of stuff on NEAR as a linkdrop.

I mean in the sense that you just create new KeyPair and then make regular smart contract functionCall transaction to whatever linkdrop contract you want to use
