PLS staking dashboard Adjustd for Mainnet

Based by Yoldark's + raskitoma work.

Requirement

Grafana 8
Prometheus with more than 30 days of data retention
Cryptowat (optional) << I don't know how to configure this. Any help will be appreciated!
Nodes: Execution, Consensus and Validator with metrics on.

Handle lot of keys
Display annualized % (kind of)
~~Support currency conversion thanks cryptowat~~ << This have not been implemented yet!
Displays PLS gains
Display status of validators (was very hard to do)
Built in alerts
Display attestation, aggregate and proposed count per validators
Keep tracks of daily and monthly income

~~Add aggregated and proposed blocks in the validator table (there is only attestation right now)~~

~~Cpu usage can't be displayed as it is not provided~~ Load avg added which should be a suitable solution.
~~Process starting time is an educated guess as not provided, it should be enough~~ Metrics implemented in Tony release, i use them now
The bottom node graph is supposed to display global balance for exited and withdrawable validators. This is not the case as lighthouse do not provide this info.
~~Log types counter are merged, need warning and error counter~~ It is because there is no error logs
