PnL Reporting UI

[hilkoc]

• What kind of change does this PR introduce? (Bug fix, feature, docs update, ...)
  This pull request adds a new tab to the Gekko UI for PnL reporting. Details in this issue Improved PnL reporting #2028
  The PnL page looks like this:
  

• What is the new behavior (if this is a feature change)?
  Backend code fetches all (new) trades from the exchange and stores them in sqlite database.
  In the UI, all new trades since the last sync with the exchange are shown.

For each buy trade it shows how much your current position and average open price changed.

For each sell trade it shows how much was gained (take profit) or lost (stop loss).

Below the trade level breakdown is an overview of all positions for all traded currency pairs. For each it is shown how much is invested at what average opening price and how much the PnL is, in term currency and relative as percentage.

Hey! Apologies for the delay.

I love this PR, few things:

• I am working on a major exchange overhaul, you can find the details here: [WIP] Gekko broker #2118. There is a lot of overlap between what you want and what is happening there. Mostly: Do we really need more glue code between exchanges and Gekko or can we re use the existing exchange interface? (in that PR I am improving that interface). To calculate PnL you only need to get details on trades you did (price, amount, fee, date, etc right)? Gekko already has func for that.
• I love how ambitious you are in getting this extremely complex behaviour added to Gekko, however I do plan to roll out more advanced order execution a bit more phased (starting with Gekko Broker) and it will take a while before it can hit any UI. Apologies on my end on not being very responsive in your excellent issue Improved PnL reporting #2028 and the forum (can you please post the link here again?)

I propose to talk about future features on the forum and actuall implementation details here. As such I first like to talk on the forum post you created for this topic.

This PR as it is now can be merged into the develop branch, so others can benefit from this, have a look and improve it further.
It may need some more work though before it goes into a stable release. I admit it is not well integrated with existing gekko code for interfacing with exchanges and managing API keys.

I'll say more about this on the forum https://forum.gekko.wizb.it/thread-56679.html . For now this is just first version that works and can do something useful, which I'd like to share for the benefit of others.
