idp metadata mimetype

[Liam Hoekenga]

We recently upgraded our IdP from 2.1.5 to 2.3.5, and I've noticed  
that the mimetype of the IdP's metadata has changed from  
application/samlmetadata+xml to application/xml (this also involved a  
tomcat and java upgrade..)

One of our system monitoring tests is looking specifically for  
application/samlmetadata+xml.. I could request that the test look for  
a different mimetype, but since I control the IdP, I thought it might  
be faster for me to change it on my side.

I see you can set the mimetype of the metadata in the SP.
Is it possible to specify the mimetype of the metadata for the IdP?
