[Strategies] Track data points

[danielsimao]

There are some data points for the WIP strategies page that would be nice to have squid handling them instead of the UI:

• Data about each available strategy (specially APY/APR)
• Strategy current position (such as earnings so far)

Im not sure if Im missing something @peterslany

* [ ]  Data about each available strategy (specially APY/APR)

@danielsimao Why is this needed? I think it's already provided by the lib
