Skale admin doens't print restart count and failed rpc count in schain checks.json

[oleksandrSydorenkoJ]

Describe the bug
Skale admin runs checks every minute for each Skale chain on the current node and updates the checks.json file.
These checks included config_dir, dkg, volume, firewall_rules, skaled_container, exit_code_ok, RPC, blocks, process, ima_container. We can use only logs inside the docker container to see the restart count of the chain or failed rpc-checks, but not API calls.

Preconditions:
16 nodes
At least 1 active schain

Versions
skalenetwork/admin:2.6.0-beta.0 (2.3 Release)
skalenetwork/admin:2.5.4-develop.1 (2.2.1 Release)

skalenetwork/schain:3.18.0-beta.0 (2.3 Release)
skalenetwork/schain:3.17.1 (2.2.1 Release)

To Reproduce

1. Send curl http://localhost:3009/status/schains call on the node
2. Check the result of the response
3. Check checks.json for any chain on the node

Expected behavior
The check report should return the restart count and failed RPC checks count in addition to existing config_dir, dkg, volume, firewall_rules, skaled_container, exit_code_ok, RPC, blocks, process, ima_container checks.

Actual state:
Skale admin doesn't return restart count and failed RPC count and doesn't print them into checks.json.
Example output:
