Add Events in HealthCheck

[rareweasel]

Add the corresponding events in the following functions:

• BaseStrategy.setHealthCheck.
• BaseStrategy.setDoHealthCheck.

Also, the harvest() function modifies the doHealthCheck here without emitting an event.

Output

Emit events in both functions and in the harvest function where the doHealthCheck variables is modified.

Target Tag/Branch

Since the health check is not present in the main branch, the target is v0.4.3

Hi @pandadefi are you planning to impl this? any ETA?

I saw there is a merged pr but it looks like it is not what we needed for this issue.

After 0.4.3 the heath check isn't on Base strategy but on vault to reduce Base strategy size.
