feat(findings): Add resource_tag filters for findings endpoint

[vicferpoy]

Description

New filters have been added to the following endpoints:

• GET /findings
• GET /findings/metadata

In addition, the GET /findings/metadata endpoint will not return a list of values for each tag.

Examples

Every filter is self explanatory except for the filter[resource_tags], which expects a list of key:value pairs separated by commas:

Same behavior for GET /findings
