Rename SSL_CERT_FILE to NODED_CERT_FILE
To be consistent with RAPI_CERT_FILE, the rather generic named“SSL_CERT_FILE” constant is renamed to “NODED_CERT_FILE”. The actual filename is not changed.

Implement conversion from drbd to plain

Implement conversion from plain to drbd
This patch adds a new mode to instance modify, the changing of the disktemplate. For now only plain to drbd conversion is supported, and thenew secondary node must be specified manually (no iallocator support).
The procedure for conversion works as follows:...

Add a function to validate and normalize hostnames
This differs slightly from the specification, by allowing names to startwith digits, not checking the length of individual components, andallowing underscores.
ListVisibleFiles: require normalized path names
This patch changes ListVisibleFiles to raise ProgrammerError if it'spassed a non-absolute/non-normalized path name, and adds unittests forthis behaviour.
Switch more code to PathJoin
This should remove most of the remaining constructs which can bereplaced by PathJoin.
