Replaces the pattern analysis flyout in Discover with a tab which sits
alongside the Documents and Field statistics tabs.

**Field selection**
Lists all of the text fields in the index. Auto selects `message`, then
`error.message`, then `event.original` and if none of these fields are
available, it just selects the first field in the list.

The Options menu provides some configuration options:

**Minimum time range**
Sets the minimum time range used for the pattern analysis search. The
pattern matching results results will be more accurate the more data it
sees, so if the user has selected e.g. last 15mins in the time picker,
this settings will ensure a wider time range is used to improve the
accuracy of the patterns. If the time picker has a larger time range
than this setting, the larger time range will be used.

**Random sampling**
Improves the search performance by using a random sampler. This is the
same setting as before.
