"""Setup the pipelines according to config.
The configuration is supported in one of two forms:
1. Deprecated: the source and sink configuration are conflated
as a list of consolidated pipelines.
The pipelines are defined as a list of dictionaries each
specifying the target samples, the transformers involved,
and the target publishers, for example:
[{"name": pipeline_1,
"interval": interval_time,
"meters" : ["meter_1", "meter_2"],
"resources": ["resource_uri1", "resource_uri2"],
"transformers": [
{"name": "Transformer_1",
"parameters": {"p1": "value"}},
{"name": "Transformer_2",
"parameters": {"p1": "value"}},

"publishers": ["publisher_1", "publisher_2"]
},
{"name": pipeline_2,
"interval": interval_time,
"meters" : ["meter_3"],
"publishers": ["publisher_3"]
},
]
2. Decoupled: the source and sink configuration are separately
specified before being linked together. This allows source-
specific configuration, such as resource discovery, to be
kept focused only on the fine-grained source while avoiding
the necessity for wide duplication of sink-related config.
The configuration is provided in the form of separate lists
of dictionaries defining sources and sinks, for example:
{"sources": [{"name": source_1,
"interval": interval_time,
"meters" : ["meter_1", "meter_2"],
"resources": ["resource_uri1", "resource_uri2"],
"sinks" : ["sink_1", "sink_2"]
},
{"name": source_2,
"interval": interval_time,
"meters" : ["meter_3"],

"transformers": [
{"name": "Transformer_1",
"parameters": {"p1": "value"}},
{"name": "Transformer_2",
"parameters": {"p1": "value"}},
],
"publishers": ["publisher_1", "publisher_2"]
},
{"name": sink_2,
"publishers": ["publisher_3"]
},
]
}
The semantics of the common individual configuration elements
are identical in the deprecated and decoupled version.
The interval determines the cadence of sample injection into
the pipeline where samples are produced under the direct control
of an agent, i.e. via a polling cycle as opposed to incoming
notifications.
Valid meter format is '*', '!meter_name', or 'meter_name'.
'*' is wildcard symbol means any meters; '!meter_name' means
"meter_name" will be excluded; 'meter_name' means 'meter_name'
will be included.
The 'meter_name" is Sample name field. For meter names with
variable like "instance:m1.tiny", it's "instance:*".
Valid meters definition is all "included meter names", all
"excluded meter names", wildcard and "excluded meter names", or
only wildcard.
The resources is list of URI indicating the resources from where
the meters should be polled. It's optional and it's up to the
specific pollster to decide how to use it.
