Add SearchConfig, add test, update CLI (#81)

Adds SearchConfig with `MatchType` (Exact, Regex, Contains, Startswith),
and `CaseSensitivity` (Insensitive or Sensitive), adds a test, and
incorporates into CLI with defaults for:
- `SearchText` when across all search contexts (regex)
- `MetricsId` (startswith, case insensitive)
