MINOR: servers: Support alphanumeric characters for the server templates names

'server-template' directive doesn't support the same name alphabet as
the 'server' directive. This patch allows the usage of chars [0-9].

[wt: let's backport this to 1.8 to apply the principle of least surprize
 to people migrating to server templates]
