Throw an error if plugin is executed outside of a serverless directory #5636

What did you implement:

This is a revisit of a previous developer experience bug where executing a serverless command in a path with no serverless.yml would fail silently. I noticed that this issue has returned in the latest release.

The tests appeared to be passing because the method to validate a plugins config dependency was working, but the rejection was not being caught during execution, possible because of the asynchronous nature of loading the config file in getServerlessConfigFile

How did you implement it:

getServerlessConfigFile was being called twice within the pluginManager, so serverless will now ask the PluginManager to load the config file earlier and then store it to lookup during plugin execution, rather than try to load in it's methods as it was previously.

How can we verify it:

Currently, running sls info provides no feedback when running in a directory without a serverless.yml will result in a silent failure.

Checking out this commit and try running ./bin/serverless info in a directory with no .serverless.yml will result in an error indicating that it must be executed in a serverless directory.

No documentation has been added as it's N/A.
