Isolate Jersey dependency

[basoko]

I have done a small refactor with the aim of isolate the Jersey dependency.

[nikoloff]

I like this proposal.
I will touch the methods visibility and will build a new version with it.

thx

[basoko]

Ok @nikoloff but if you want I can change the methods visibility that you think need a change and update the pull request.

Regards.

[nikoloff]

Yes thx @basoko , that will be great.
In the services package the utilities classes ParameterMap and HttpClient with it's methods should be final with package visibility.

[basoko]

Sorry @nikoloff, I'm not sure about what you mean because ParameterMap is final and HttpClient is an interface so it can not be final.
I can't change the package visibility because the HttpClient interface is needed in the PaymillContext class, so it has to have public visibility, and at the same time it depends on ParameterMap, so this last one should also be public.

@basoko sorry about the merge delay, we will take care of both pull requests next week. Again, thanks for the contribution.

Hi @nikoloff, @stoilkov is this PR alive?

[stoilkov]

@basoko sorry about the delay. will take care of this today.

[basoko]

@stoilkov Don't worry, there's no rush. I only wanted to know if there's something I can do to improve it.
