Michael Sproul 65eaf01942 VC: avoid sending fee recipients until just before merge (#3064) ...

## Issue Addressed

Presently if the VC is configured with a fee recipient it will error out when sending fee-recipient preparations to a beacon node that doesn't yet support the API:

```
Mar 08 22:23:36.236 ERRO Unable to publish proposer preparation  error: All endpoints failed https://eth2-beacon-prater.infura.io/ => RequestFailed(StatusCode(404)), service: preparation
```

This doesn't affect other VC duties, but could be a source of anxiety for users trying to do the right thing and configure their fee recipients in advance.

## Proposed Changes

Change the preparation service to only send preparations if the current slot is later than 2 epochs before the Bellatrix hard fork epoch.

## Additional Info

I've tagged this v2.1.4 as I think it's a small change that's worth having for the next release
