Provider checker API

[Zensey]

Summry of task:
Essentially, the program should get the connection parameters from the API, raise the connection and make sure that it works.
Establishing a VPN connection to wireguard must be done through the wg+gvisor combination, because raising a real network interface is not convenient especially in could environments, so a VPN connection that works entirely from code would be very useful.

Implementation notes:
Check of provider's functioning is done by requesting to http://107.173.23.19:8080/test

How to build
go run mage.go buildProvChecker

Example of use
.\build\myst\myst.exe --provchecker --log-level=error daemon

Example of use #2 (with postgres - to save results of scan into table)
.\build\myst\myst.exe --provchecker --log-level=error --checker.dsn="host=yyy user=mypguser password=xxx dbname=myst_nodes port=5432 ss
lmode=disable" daemon

Api
http://localhost:4050/prov-checker?id=0x020dd683990895d0f81a47702161f1d29d209976

Response:
{"status":true,"error":null,"provider_id":"0x020dd683990895d0f81a47702161f1d29d209976"}

Batch mode (check many providers):

curl.exe -vvv -H "Content-Type: application/json" \
  http://localhost:4050/prov-checker-batch \
  -d '["0x020dd683990895d0f81a47702161f1d29d209976","0x1a52807858619c4acb2a075b659a86dbe459bc98"]'

Response:

[
  {
    "status": false,
    "error": "err_connect",
    "provider_id": "0x020dd683990895d0f81a47702161f1d29d209976"
  },
  {
    "status": true,
    "error": null,
    "provider_id": "0x1a52807858619c4acb2a075b659a86dbe459bc98"
  }
]

Batch mode #2 (check all providers of a given country or gloabally):

curl.exe -vvv -H "Content-Type: application/json" \
  http://localhost:4050/prov-checker-batch2?location=US

Do we have a task for this with requirements? From now it looks like it duplicates what we have for providers checks in the monitoring agent.

The difference from monitoring agent is the capability to function w/o using OS-based network interfaces, thus making it more cloud-friendly or suitable for non-Linux (e.g. Windows). One of the real applications of that API is search of provider nodes affected by bug #6022
