Allows add custom message to report

Problem to solve

Have a better description of what test fail

Idk, if my approach is correct, but actually i am having multiple request in a single file to test a API functionality however, hurl just return something like

error: Assert failure
  --> user-reads.hurl:83:0
     |
     | POST {{BASE_URL}}/userReads
     | ...
83 | jsonpath "$.data.dailyIncrement" == 0
     |   actual:   float <6.520000457763672>
     |   expected: int <0>
     |

Proposal

My idea is that hurl could allow to add a error description, like

error: Assert failure
  --> user-reads.hurl:83:0
     |
     | POST {{BASE_URL}}/userReads
     | ...
83 | jsonpath "$.data.dailyIncrement" == 0
     |   actual:   float <6.520000457763672>
     |   expected: int <0>
     |
     | description: If initial date is one day before end date, daily increment should be 0

in .hurl file the option could look like this

POST {{BASE_URL}}/userReads
[Asserts]
description:  If initial date is one day before end date, daily increment should be 0

This will help me to have a cleaner idea of what the test does.

Tasks to complete

• Display custom message when an error appear
• Allows to add a custom message in [Asserts] section
• Update the docs, that explain how to use this functionality
