Proposal of tweaks around global and local cache configuration

[kdybicz]

• Making sure global cache configuration is taken into consideration for all datasource methods
• Making sure method-specific cache configuration is overriding global configuration, if present
• Adding related tests
• Adding VSC configuration folder to .gitignore

@StarpTech I'm happy to talk through the changes I've made and the motivation, I also have following changes queued up, ie. for optional maxTtlIfError and I'm thinking on improving performance and bandwidth used while caching with maxTtlIfError

Hi @kdybicz sorry for the late response. Your change will give request options precedence over global defaults. This is natural and the current behavior was more of a bug.
