fmd: enable reload of configuration without restart [#2923]

Only FMS_PROMOTE_ACTIVE_TIMER, FMS_NODE_ISOLATION_TIMEOUT and
FMS_ACTIVATION_SUPERVISION_TIMER are currently supported.

These values can be changed in fmd.conf and take effect
by sending SIGHUP to fmd.

base: add config file reader [#2923]

Some configuration attribute are read by OpenSAF daemons as
environment variables. eg.

export FMS_PROMOTE_ACTIVE_TIMER=0

There is no easy way to reload these values without a restart.

ConfigFileReader will parse these files looking for 'export VAR=VAL'
and store them into a map, so a daemon can reload configuration
without a restart.
