feat: add filtering by tags and names

[vigneshshanmugam]

• fix Add tags, filtering #26
• Added support for glob pattern matching for both journey name and tags.
• Names and tags can be matched with multiple journeys that has the same name and tags spawned across multiple files.

elastic-synthetics examples/todos/* --match 'check*' 
// will match all the journey that has `check` in their name and tags. 

This aligns with RegExp or glob matching found in major libraries like jest, folio, mocha etc and we don't support variadiac options for name matching as majority of the cases can be solved with a mix of both.

• Tags matching which is a variadic option meaning you can pass multiple options in the CLI to match a group of journeys.

// will run the journeys that are tagged with the respective teams in the kibana repo. 
elastic-synthetics <dir> --tags 'kibana:uptime*'  'kibana:apm*'

journey({ name: "elastic uptime app", tags: ["kibana:uptime", "kibana:apm" }, () => {})

Note: match pattern that matches both name and tags, tags pattern that matches only tags

@spalger Curios to hear if these options would work for Kibana apps?
