Please allow mariadb docker image
Tried to run crabgrass tests with maria db to prepare for migration to stretch.
Turns out the corresponding docker image is not allowed. Please add it to the list of allowed images. Here's the job that failed: Job #21206 failed for riseuplabs/crabgrass@dd007ba535e3bbd2320bebb6bc306ffa632fb7ba
The required image is mariadb:10.1
