* app/vmalert: add retries to remotewrite
Remotewrite pkg now does limited number of retries if write request failed.
This suppose to make vmalert state persisting more reliable.
New metrics were added to remotewrite in order to track rows/bytes sent/dropped.
defaultFlushInterval was increased from 1s to 5s for sanity reasons.

The change adds no new functionality and aims to move flags definitions
to subpackages that are using them. This should improve readability
of the main function.
app/vmalert: add support for TLS configuration
Add support for TLS optional configuration in a similar fashion to what
is currently supported in other vmutils such as vmagent. TLS
configuration options are distinct for datasource, remoteRead,
remoteWrite as well as notifier.
* vmalert: Add recording rules support.
Recording rules support required additional service refactoring since
it wasn't planned to support them from the very beginning. The list
of changes is following:
* new entity RecordingRule was added for writing results of MetricsQL
expressions into remote storage;
* interface Rule now unites both recording and alerting rules;
* configuration parser was moved to separate package and now performs
more strict validation;
* new endpoint for listing all groups and rules in json format was added;
* evaluation interval may be set to every particular group;
* vmalert: uncomment tests
* vmalert: rm outdated TODO
* vmalert: fix typos in README
* feat: add remoteWrite.maxQueueSize to reduce queue full
* rename remote(write|read) flags to remote(Write|Read) for the sake of consistency
