Julien Pivotto 3856195bb8 tsdb: use float64 for retention percentage

The retention.percentage config field was typed as uint, which silently
truncated fractional values. Setting percentage: 1.5 in prometheus.yml
resulted in a retention of 1%, with no warning or error.

Remove the redundant MaxPercentage > 100 clamp in main.go; the config
UnmarshalYAML already returns an error for out-of-range values before
this code is reached.
