Volunteer can click to edit foster information

[maggie-larkin]

Notes

• Volunteers should have the ability to edit foster information. Say a foster texts a volunteer and says "I have to go out of town on the 8th" the volunteer will want to update the fosters availability (we dream of self service but that's while away yet)
• See here for the mock
