enableTagOverride value being written as a quoted string, need to be unquote boolean.

[sjoeboo]

The recent addition of the enableTagOverride service config option seems to be writing the value as a quoted string:

"enableTagOverride":"false"

Which cause consul to fail to load the service:

Jun  2 11:06:09 dev01 consul: ==> Error decoding '/etc/consul/service_slurmctld.json': 1 error(s) decoding:                                                               │·
Jun  2 11:06:09 dev01 consul: * 'EnableTagOverride' expected type 'bool', got unconvertible type 'string'

Removing the quotes around false, allows it to load:

"enableTagOverride":false

I'll see if i can work up a fix and submit a pr, but wanted to file the issue now.
