We must change the REST API to get templates by scope

Xporter should have a different approach in order to get templates by Scope.
Until now, Xporter uses the following request to get all the Structure templates:

http://localhost:8080/rest/jiraxporter/1.0/templates/byScope/[7]

And we must have to change the request to use numbers instead of an array.
For example:

http://localhost:8080/rest/jiraxporter/1.0/templates/byScope/7

Please, be aware we also need to check this solution for Scheduled Reports.

In order to reproduce this error:
Please, set up an environment using a simple reverse proxy (nginx) (Atlassian Documentation).
After this, please, try to get all the templates by scope using the REST API:

http://localhost:8080/rest/jiraxporter/1.0/templates/byScope/[7]

Expected Result:

java.lang.IllegalArgumentException: Illegal character in path at index 68
