Access using: http://mgmt_url/bpl/getAllPVs - Get all the PVs in the cluster. Note this call can return millions of PVs
pv An optional argument that can contain a GLOB wildcard. We will return PVs that match this GLOB. For example, if pv=KLYS*, the server will return all PVs that start with the string KLYS. If both pv and regex are unspecified, we match against all PVs.
regex An optional argument that can contain a Java regex wildcard. We will return PVs that match this regex. For example, if pv=KLYS*, the server will return all PVs that start with the string KLYS.
limit An optional argument that specifies the number of matched PV's that are retured. If unspecified, we return 500 PV names. To get all the PV names, (potentially in the millions), set limit to –1.
