This fixes a regression introduced in #16646 where using Elasticsearch 
pre-v7.0 and alerting resulted in an error when trying to deserialize the 
response of total number of hits.
Total number of hits is not in use by the backend so we're removing it 
for now to make ES 6 and 7 being able to deserialize search responses 
without errors.

Closes #15622

Fixes #16880

When allow_embedding is false (default) the Grafana backend 
will set the http header `X-Frame-Options: deny` in all responses 
to non-static content which will instruct browser to not allow 
Grafana to be embedded in `<frame>`, `<iframe>`, 
`<embed>` or `<object>`.

Closes #14189

Several pkg/tsdb tests fail to compile on 32bit platforms due to
integer overflow.

Currently all API requests set Cache-control: no-cache to avoid browsers 
caching sensitive data. This fixes so that all responses returned from 
backend not are cached using http headers. The exception is the data proxy 
where we don't add these http headers in case datasource backend needs 
to control whether data can be cached or not.

Fixes #16845

A new parameter `queryMode` is added to the InfluxDB datasource to provide a way to use POST instead of GET when querying the database. This prevents to get any error when querying the database with a heavy request.
Default configuration is kept to GET for backward compatibility. Tests and documentation have been added for this new behaviour.

Datasources: Add pattern validation for time input on datasource config pages

* Added search-query-parser package

* Migrate search input field to react and enable current folter filtering

* Search: have clear reset query as well

This fixes a regression introduced by #16724 when datasource is configured
to use HTTP method POST and testing the datasource which results in an
'options.headers is undefined'. Same error probably happens if datasource
is configured to use basic auth and testing datasource.
