Support customized server config

[zhongnansu]

Issue #, if available:

98

This is the most reported issue so far. Users are not able to generate any report if they have customized Kibana sever setting(host, sever base path, port), or enable TLS.

Server config is set in kibana.yml

Description of changes:

• remove the hardcoded localhost:5601 when building the complete url
• Dynamically retrieve serverInfo(which contains port, host, protocol), and server.basePath and pass them through route handler for validating the input url, compose complete url.
• Add one more puppeteer launch option ignoreHttpsError: true to support TLS-enabled kibana server https://github.com/puppeteer/puppeteer/blob/main/docs/api.md#puppeteerlaunchoptions
• Add one more param "path: server.basePath" to the cookie object, to support customized server.basePath when security is enabled.
