Fire page migration - Get a hazardous materials permit info/service page and form

### Page or pages that needs to be migrated:
service page:
https://www.austintexas.gov/department/afd-permits
https://www.austintexas.gov/department/hazmat-permit
http://www.austintexas.gov/sites/default/files/files/Fire/Prevention/Permits/ExistingCO2.pdf
http://austintexas.gov/page/outdoor-liquified-petroleum-gas-installation-request

Forms:
https://www.austintexas.gov/sites/default/files/files/Fire/Prevention/HazMatApp.pdf
http://austintexas.gov/sites/default/files/files/Fire/Prevention/Outdoor_LPG_Installation_Request_01052018.pdf

**Note: I think its possible there should be an info page about hazardous materials, and then two service pages for the two different processes.
