telemetry(cwl): fix LiveTail metric definitions aws#932

## Problem
Addresses feedback on
aws#916

## Solution
* Uses `hasTextFilter` instead of defining a new
`hasLogEventFilterPattern` property
* Defines a more generic `filterPattern` type, as an enum that supports
logStream filter type strings
* renames metrics to `cloudwatchlogs_startLiveTail` and
`cloudwatchlogs_stopLiveTail`
