Fix Sse client api

[pawanjay176]

Issue Addressed

N/A

Proposed Changes

The get_events api in BeaconNodeHttpClient uses a regular http get request to stream the events. This doesn't handle a lot of sse params like return of partial bytes, maintaining a heartbeat etc. Using the get_events stream as an api consumer led to the connection getting repeatedly cutoff.
This PR uses reqwest_eventsource to do the sse handling.

Additional Info

Using reqwest-eventsource v0.5 to keep the reqwest version same as what we use in lighthouse.
