Simpler OID in generated certificates
As many softwares doesn't support 128 bits long arc in OID (see https://misc.daniel-marschall.de/asn.1/oid_facts.html#chap4), we registered a simpler OID through https://oidplus.viathinksoft.com).
OID 1.3.6.1.4.1.37476.9000.70 is for Nexedi (https://oidref.com/1.3.6.1.4.1.37476.9000.70). OID 1.3.6.1.4.1.37476.9000.70.0 is for Caucase (https://oidref.com/1.3.6.1.4.1.37476.9000.70.0).
