Add: python monero health checker module

[normoes]

I would like to introduce monero_health to you. It is written in python and is a module to return health or status information about monerod.

https://github.com/normoes/monero_health

The README describes its usage and responses.

This module is used on the XMR.to community hub - The module provides the running serice with the JSON result.

• https://community.xmr.to/node/mainnet/health/api/v1/monerod/health
• https://community.xmr.to/node/mainnet/health/api/v1/last_block
• https://community.xmr.to/node/mainnet/health/api/v1/last_block/health

The idea is to make the monero daemon status available in a readable format, right now only JSON.

Definition of status (see README):

• There are the P2P and the RPC status - This is essentially about connectivity + information like the hardfork version. Both are combined in the status found at /monerod/health.
• There is the last_block status, which defines an age limit (12 [minutes]) of a block and returns OK if the block is younger than that or ERROR if the block is older than that.

What do you think?

This is good. A nice python module which could be easily integrated. Remote node health is important for Monero service project. I vote ACK.

Cool project. ACK for me as well, but @normoes could you add a license? I think it's important that for the nature of the Ecosystem project itself, all projects should be licensed, to not make contribution/distribution hard.

[normoes]

Good point. LICENSE added.

@monero-ecosystem/maintainers any opinion/vote about this?

[emesik]

ACK from me, definitely. This seems very useful, especially when monerod is not a super reliable piece of software.

Thank you for voting. We can consider this accepted. @normoes you may start the transfer whenever you are ready. Please ping me when it's done :)
