The storage filters are modified to use the predicates directly so we do
not have to pass `semantic.FunctionExpression` around. Instead, since
simple expressions are all that are supported anyway, we transform
suitable function expressions into predicates as part of the push down
rule and this simplifies the influxdb reader code.
This also moves the storage predicate conversion code into the standard
library package as it is the only location that uses this code now that
the predicate conversion is done as part of the push down rule.
This refactor was prompted by another refactor of the
`semantic.FunctionExpression` that would cause it to always contain a
`semantic.Block`. Since the push down filter needs the expressions and
to combine them, this refactor allows us not do construct a combined
filter inside of blocks which allows us to have better type safety.

These APIs require a measurement, permitting an additional optimization
to reduce the search space against the TSM index. Specifically, the
search key prefix is extended from `org+bucket` to
`org+bucket,\x00=<measurement>`

* MeasurementTagKeys
* MeasurementTagValues
* Adds an api to the models package for efficiently parsing the
measurement tag (\x00) from a normalized series key

The root cause is that the Unsigned data type has no representation
in the valueType function in the cache and falls back to the default
case of 0.
0 is also a sentinel value in the entry#add function that will
result in skipping the value type check.
It therefore is possible that unsigned values followed by some other
data type is stored in the cache.
It is suspected that the write may be rejected before reaching the
cache, and therefore may not occur in practice. Specifically, the
series file stores the data types on a per-series basis and would
reject the write.
This commit turns the value types into explicit constants and
ensures all existing block types are represented. In addition,
it adds a mapping function to convert these to a known Block type,
which will be used by the `MeasurementFields` schema request to
determine the type of a series in the cache.
At the moment, the default session length only gets set to the default
when no service config is specified. So if a service config is used and
it does not set a value for the session length, then the session length
will be zero.
This modifies the creation of the kv service so that it will set the
default session length if the session length is set to zero (the default
value) instead of only doing it when no service config is specified.
