Fix metaField/requestField/responseField types

[davidgoli]

Addresses #256

[lmeerma]

When is this going to be merged?

[bithavoc]

the real changes we need to merge I believe are:

 metaField?: string | null;
    requestField?: string | null;
    responseField?: string | null;

I don't know about the rest. I can merge and release if you rebase with only those changes. We can open another issue to address the rest of the base interface refactoring.

[bithavoc]

Please only include changes for metaField requestField and responseField.

[lmeerma]

@bithavoc I agree, my problem would be fixed when only metafield, requestField and responseField are changed.

[davidgoli]

@bithavoc Changes made, please take another look

[bithavoc]

Great, I agree there is some repetition, but we can fix that in another PR. I'm ready to merge, do you want to rebase to squash your commits in a single commit or you want github to do it?

[davidgoli]

@bithavoc done
