Bifrost: set TFTP cache master path properly

Browse Source 
Ironic creates hardlinks between the TFTP master image store and the
HTTP root path when iPXE is enabled. With Docker volumes used for these
locations we run into https://bugs.launchpad.net/ironic/+bug/1507894
during deployment. If we use a directory under /httpboot to store the
master images this issue is avoided.

This change uses the new bifrost config variable,
ironic_tftp_master_path added in [1] to configure the path, rather than
the existing hacked approach of modifying the ironic.conf config file
after the bifrost_deploy container has started.
