Huyen Chau Nguyen 77b4fbb69c Fix maxspeed to consider source:maxspeed tags (#5217) 
* In Belgium the maximum speed in rural areas is 70 in the region Flanders
* parse maxspeed using source:maxspeed and maxspeed:type tags
* add changelog
* make maxspeed:advisory more important than maxspeed
* add test for source:maxspeed

Feature: Car - Max speed restrictions
OSRM will use 4/5 of the projected free-flow speed.
Background: Use specific speeds
Given the profile "car"
Given a grid size of 1000 meters
Scenario: Car - Respect maxspeeds when lower than way type speed
Given the node map
"""
a b c d e f g
"""
And the ways
| nodes | highway | maxspeed |
| ab | trunk | |
| bc | trunk | 60 |
| cd | trunk | FR:urban |
| de | trunk | CH:rural |
| ef | trunk | CH:trunk |
| fg | trunk | CH:motorway |
When I route I should get
| from | to | route | speed |
| a | b | ab,ab | 85 km/h |
| b | c | bc,bc | 48 km/h |
| c | d | cd,cd | 40 km/h |
| d | e | de,de | 64 km/h |
| e | f | ef,ef | 80 km/h |
| f | g | fg,fg | 96 km/h |
Scenario: Car - Do not ignore maxspeed when higher than way speed
Given the node map
"""
a b c d
"""
And the ways
| nodes | highway | maxspeed | # |
| ab | residential | | default residential speed is 25 |
| bc | residential | 90 | |
| cd | living_street | FR:urban | |
When I route I should get
| from | to | route | speed |
| a | b | ab,ab | 25 km/h |
# default residential speed is 25, don't mess with this
| b | c | bc,bc | 72 km/h |
# parsed maxspeeds are scaled by profile's speed_reduction value
| c | d | cd,cd | 40 km/h |
# symbolic posted speeds without explicit exceptions are parsed
# from the profile's maxspeed_table_default table
Scenario: Car - Forward/backward maxspeed are scaled by profile's speed_reduction if explicitly set
Given a grid size of 100 meters
Then routability should be
