Remove Kharkov

[EGI-ILM]

I think this site has been removed: EGI-Federation/fedcloud-catchall-operations#216
and it is affecting operation

egiilm@tckr:~$ fedcloud site list

Error during reading data from https://raw.githubusercontent.com/EGI-Foundation/fedcloud-catchall-operations/main/sites/Kharkov-KIPT-LCG2.yaml

It would be good to either retrieve this list dynamically from somewhere or to implement exception management in the same way we did for the certificates, so the program operation is not interrupted if one of these YAML files cannot be accessed.

The location of the site list is already planned in the configuration file #86:

overwriting default values of some constants in the codes: e.g. timeout, site configurations, ...
Example of use cases: users of some VOs/RIs may prefer to have a customized list of only sites supporting the VOs/RIs in fedcloudclient site configurations, not all sites registered in GOCDB. That can speedup all-sites operations.
NGIs can have their own lists of sites

The issue has been marked as high priority for a long time, several other issues are pending on it.
