feat(analyzer): enable host os info analyzer to support multiple nodes

[DexterYan]

Description, Motivation and Context

following PR #1608

• enable host info analyzer to analyzer multiple nodes
• save node list into system/hostos_info_nodes.json
• split collect results into system/nodename/hostos_info.json
• analyzer result and add node name in the title
• add tests

LGTM, only 1 nit suggest

[xavpaice]

the main thing to review here is that we have a ..._nodes.json that lists the nodes which were collected, and the analyzer then uses that to find the appropriate files. We chose this over wildcard as it is more precise, a wildcard could pick up stuff we don't want if we later change the collector to add more files (like raw output).

[DexterYan]

Now the code has been improved to create only one file called node_list.json which has all the node name. It can be used for all host collectors without duplicated.
