Remove the redundant `wheel` dependency, as it is added by the backend automatically.

Listing it explicitly in the documentation was a historical mistake and has been fixed since,
see: [pypa/setuptools@f7d30a9](pypa/setuptools@f7d30a9).

This commit adds a new file with the SHA1 of commits to ignore when
running git blame. This is important because of the recent adoption of
black and clang-format as our code formatting tool in Qiskit#1630 we caused a
large amount of code churn to change the code formatting. However, using
the ignore file is a local opt-in feature for git and not something we
can enable globally by default. To facilitate this a section is added to
the bottom of the contributing guide to document how this file can be
used.

Essentially equivalent content is already incorporated in Qiskit#1739.

* Fix wrong set of parameters in circuits with barriers

`AerCircuit` is created from a circuit by iterating its instrucitons
while skpping barrier. This leads inconsistency with positions of
parameter bindings. This commit adds barrier instruction to the class
and keeps positions of parameter bindings.

* remove unused variable in test

This commit reduces redundant copy in `AER::Transpile::CircuitOptimization`.
Since 0.12.0, configuration is `AER::Config` instead of `json_t`. This new class
has many fields and then its copy overheads become high. Reduction of
redundant copy improves performance especially for low-qubit simulation.

… dependency (Qiskit#1804)

Since qiskit-terra 0.24, `Sampler` does not have `close()` but Aer's `Sampler` still have the method. This commit takes the method as well as upgrade of Python versions in tutorial tests from 3.7 to 3.8.

* rm close

0.12.0 accidentally removed MPI support if application does not use qobj. This commit reverts the change.

* Add implicit cast of argument types

Since 0.12.0, AerConfig is used to configure simulation, which
is directly bound to a AER::Config object through pybind.
This change requires application to specify strictly correct types
of configuration options. This commit allows implicit casting
to arguments if application specifies them with wrong types.
This commit resolves Qiskit#1754.

* does not warning in cast of numpy classes if they are compatible with expected type

* Support parameterized global phase

Though `ParameterExpression` can be set to `QuantumCircuit.global_phase`,
Aer does not bind parameter values to it in simulation phase. This commit fixes
this problem by resolving values of `global_phase` with specified `parameter_binds`
in `AerSimulator.run`.

* define AER::CONFIG::GLOBAL_PHASE_POS and its pybind

This commit fixes this behavior to return a real value.

…iskit#1772)

* Stop using circuit metadata to internaly manage simulation results

This fixes `AerSimulator` to use circuit metadata to maintain mapping
from input and output of an executor call. This fixes an issue
Qiskit#1723.

* add index of AER::Circuit and ExperimentResult

* add a link to an input circuit in each experiment result

`Estimator` in Aer did not use parameter bindings appropriately. Backend is called multiple times 
to simulate a circuit with multiple parameter-sets. This commit is to call backend once for multiple
parameter-sets for a circuit.

Previously `QuantumCircuit.initialize` was not correctly preocessed
if initial state is specified with single `int` value. This commit
fixes this issue by decomposing initialize instructions.
