Analyse the integration with Xray API

At this moment the integration flow is the following:

We need to generate API Keys for each user, this will be done by an admin.

Each user will configure the integration with this keys and this token will be used in GraphQL to request Xray data.

After that we already have the user token. We just need to make the requests and refresh the token when expired.

However, the Xray Integration doesn't handle permissions when generating token. 

When we make a request we can have 2 different type of data:

• Xray related info, test steps, etc. This permissions will not be managed by Xray.
• Jira related info, key, summary, etc. This will be fixed in the future.
