[mozts2005]

add support for dot/period in the key of a setting.

when escaped it should look something like this.

vcap: services: p.mysql:

• name: Testing instance_name: testing binding_name: credentials: hostname: localhost hostnames:
  • localhost jdbcUrl: jdbc:mysql://localhost:3306/identity?user=testuser&password=testpassword&useSSL=false name: identity password: testpassword port: 3306 uri: mysql://testuser:testpassword@localhost:3306/identity?reconnect=true username: testuser syslog_drain_url: volume_mounts: [] label: p.mysql provider: plan: db-small tags:
    • mysql the name key should map to "vcap:services:p.mysql:0:name" not vcap:services:p:mysql:0:name"
