* refactor: move from io/ioutil to io and os package
The io/ioutil package has been deprecated as of Go 1.16, see
https://golang.org/doc/go1.16#ioutil. This commit replaces the existing
io/ioutil functions with their new definitions in io and os packages.

* chore: remove //nolint:gosec for os.ReadFile
At the time of this commit, the G304 rule of gosec does not include the
`os.ReadFile` function. We remove `//nolint:gosec` temporarily until
https://github.com/securego/gosec/pull/706 is merged.

* cli: fixed remaining testability indirections for output and logging
* cli: added cli.RunSubcommand() which is used in testing to execute a subcommand in the same process
* tests: refactored most e2e tests to invoke kopia subcommands in-process
* Makefile: enable code coverage for cli/ and internal/
* testing: pass 'testing' tag to unit tests which uses much faster (insecure) password hashing scheme
* Makefile: push coverage from PRs again
* tests: disable buffer management to reduce memory usage on ARM
* cli: fixed misaligned atomic field on ARMHF
also temporarily fixed statup-time benign race condition when setting
default on the timeZone variable, which is the last global variable.
* ci: refactored CI/CD logic & Makefile
- removed all travis CI emulation environment variables and replaced with:
CI_TAG=<empty>|tag
IS_PULL_REQUEST=false|true
- refactored all OS and architecture-specific decisions to use around standard GOOS/GOARCH values instead of uname/OS
- re-added self-hosted runner for ARMHF (3 replicas)
- added brand new self-hosted runner for ARM64 (3 replicas)
- disabled attempts to publish and sign on forks
- improved integration test log output to better see timings and sub-tests
- print longest tests (unit tests and integration) after each run
- verified that all configurations build successfully on a clone (jkowalski/kopia)
- run make setup in parallel
* testing: fixed tests on ARM and ARM64
- fixed ARM-specific alignment issue
- cleaned up test logging
- fixed huge params warning threshold because it was tripping on ARM.
- reduced test complexity to make them fit in 15 minutes
* testing: prevented spurious test flakes caused by kopia subprocesses messing with stderr
This was not causing actual failures, but misreporting error messages.
* testing: ensure random names are always unique by adding a counter
Globally replaced all use of time with internal 'clock' package
which provides indirection to time.Now()
Added support for faking clock in Kopia via KOPIA_FAKE_CLOCK_ENDPOINT
logfile: squelch annoying log message
testenv: added faketimeserver which serves time over HTTP
testing: added endurance test which tests kopia over long time scale
This creates kopia repository and simulates usage of Kopia over multiple
months (using accelerated fake time) to trigger effects that are only
visible after long time passage (maintenance, compactions, expirations).
The test is not used part of any test suite yet but will run in
post-submit mode only, preferably 24/7.
testing: refactored internal/clock to only support injection when
'testing' build tag is present
